Objective: To determine the value of CT screening in detecting heroin packets hidden in body and to reveal the CT features. Methods: We collected 158 cases of suspected drug packers’ imaging materials(all underwent CT, 42 cases were imaged using plain X-ray film) from September 5th, 2005 to April 23rd, 2008. Abdominal-pelvic CT appearances(shape, size, number, location and density) and abdominal plain X-ray film manifestations were retrospectively observed for those who were finally confirmed as heroin body packers through the passing of evacuated drug packets. Results: Among 158 cases of suspected drug packers in our study, 124 cases were finally diagnosed as heroin body packers. This was consistent with the CT results. However, there were 2 false-negative cases of abdominal imaging taken with plain X-ray film. All of the evacuated heroin body packets were produced mechanically. CT and plain film characteristic findings included the presence of uniform shape, varied density, and well-defined round or ovoid intra-luminal foreign-body shadows arranged closely along the gastrointestinal tract and/or vagina. We also found that the “air-ring sign” and “onion sign” were valuable characteristics that were seen on the CT scan, which helped to positively confirm the detection of heroin packets. Conclusion: Heroin body packing has clearly defined diagnostic features that can be seen with CT. Furthermore, conventional abdominal-pelvic CT is the imaging modality of choice in the evaluation of suspected body packers.

Objective: To explore the relationship between the uncommon CT findings of renal clear cell carcinoma with pathology and to evaluate it’s clinical value. Materials and Methods: Seventeen cases with renal clear cell carcinoma confirmed by surgical pathology underwent spiral CT plain scanning and dynamic enhancement scanning before operation, the CT data were reviewed and analysed retrospectively in comparison with surgical and pathological results. Results: Twenty renal lesions and 3 lesions outside of kidney were revealed in these 17 patients. Lesions located in the right kidney(n=13) and in the left kidney(n=7). The center of lesions located in the cortex of kidney(n=14) and between the medulla and the cortex of kidney(n=6). The lesions appeared as round or ellipse in shape with the mean diameter of 4.7cm(range 1.7 to 8.3cm). The CT value of the plain scan, corticomedullary phase and nephrographic phase were 11.4~34.0HU(with a mean value of 20.9HU), 27.3~112.5HU(with a mean value of 48.2HU) and 36.4~77.4HU(with a mean value of 53.7HU) respectively. The margin and the necrosis of tumor were well showed in nephrographic phase. Two adrenal pheochromocytomas and 1 islet cell tumor in the pancreatic tail were revealed outside of kidney. Conclusion: The uncommon CT findings include: insufficient blood supply, cystic, sarcomatous change and bilateral multiple renal lesions. The CT findings are correlated with histologic type, cell differentiation, vascularization and biological behaviour. Recognization the uncommon CT findings is helpful to improve the accuracy of diagnosis and pathological typing.

DOI:
Objective: To evaluate the ultrasonic features of Hashimoto’s thyroiditis(HT) with different thyroid functions. Methods: Ultrasonography was performed in 71 patients who were diagnosed as having HT. The patients were classified into three groups, the first group consisted of 26 patients with hyperthyroidism, the second group consisted of 24 patients with hypothyroidism and the third group consisted of 21 patients with euthyroidism. Ultrasonography(Philips, IU-22, America) was performed using high-frequency linear-array transducer(5~12MHz). The magnitude of thyroid gland and the diameter of superior thyroid arteries(STA), the sonographic features of thyroid gland were evaluated by gray scale sonography; subsequently color Doppler flow imaging(CDFI) was used to measure the peak systolic velocity(PSV), end of diastolic velocity(EDV) and resistance index(RI) of STA. Results: ①The width, thickness of the lateral lobe and the thickness of the isthmic portion in three HT groups were greater than those in the normal control. There was a significant difference(P＜0.05) between the thicknesses of the gland in each group. The length in the HT hyperthyroidism group was greater than that in the others. ②Focal hypoechoic pattern and diffuse hypoechoic pattern were mainly seen in the groups of HT hyperthyroidism and HT euthyroidism, diffuse hypoechoic pattern with heterogeneous linear hyperechoic and nodular changes were mainly seen in the HT hypothyroidism group. ③Normal subjects had CDFI pattern 0(absent or minimal intraparenchymal spots). Patients with HT euthyroidism had CDFI pattern 0 and pattern Ⅰ(presence of parenchymal blood flow with patchy uneven distribution). Patients with HT hypothyroidism had CDFI pattern Ⅰ and pattern Ⅱ(mild increase of color flow Doppler signal) except two cases no blood signal. Patients with HT hyperthyroidism had CDFI pattern Ⅱ and pattern Ⅲ(marked increase). ④There was a significant difference(P＜0.05) between the PSV of the STA in each group. The RIs in the three HT groups was respectively greater than that in the normal control. There were no significant differences among the three HT groups by compared with each other.⑤The PSV in the HT hypothyroidism was related with serum TSH levels(P＜0.05). Conclusions: To some extent, ultrasound can be used to evaluate the thyroid function of Hashimoto’s thyroiditis.

DOI:
Objective: To approach the diagnostic accuracy of echocardiography, multi-slice spiral CT angiography(MSCTA) of persistent fifth aortic arch(PFAA) and modify the description of PFAA by developing a new classification system． Methods: Echocardiogram and MSCTA of three selected PFAA cases were retrospectively analyzed with the current classification and the new classification. Results: One case of type A1(type Weinberg-A), one case of type A2(type Weinberg-B) and one case of type A3(abnormal origin of brachiocephalic artery) could be visualized clearly and directly by MSCTA. Morphology of PFAA and its flow disturbance could be seen on echocardiogram in cases of type A1 and type A2, although the other case of type A3 was miss diagnosed due to ignoring the suprasternal views. Conclusions: The anatomical and hemodynamic characteristics of PFAA can be accurately diagnosed by echocardiography combined with MSCTA. This new classification includes all of the potential PFAA and facilitates their analysis.

ZHENG Hong-ming;CHEN Ying-min
DOI:
Objective:　To study the clinical implications of left ventricular transient ischemic dilation(TID) with extensive myocardial ischemic coronary artery disease in aged people. Methods: Thirty aged patients with extensive myocardial ischemic coronary artery disease from 356 outpatients and inpatients, and 40 without myocardial ischemic coronary artery disease(control group and aged control group) individuals were enrolled in this study. SPECT scintigraphy imaging of stress/rest myocardial perfusion were completed after iv. injection of 740MBq 99Tcm-MIBI. Degree of coronary artery disease and ischemia were graded with SSS and SDS. Record TID calculated with software in-synchronism.　Results: TID in aged patients with extensive myocardial ischemia and those without ischemia was 1.09±0.15, 1.00±0.09 and 0.99±0.08, respectively(t=－2.50, t=－2.89, P<0.01). There was a significant difference. In aged CAD patients, area under the ROC curve was 0.707(aged control group), the best criterion was 1.02, sensitivity was 70%, specificity was 75%; area under the ROC curve was 0.739(younger control group), the best criterion was 1.14, specificity was 100%. Conclusion: The results suggest that TID assessed using the stress/rest sestamibi SPECT is a useful index for separating extensive myocardial ischemia from those without ischemia in aged people.

DOI:
Objective: To observe dynamic changes of lung parenchyma with acute pulmonary embolism(PE) in rabbit model and correlation with pathological findings. Methods: Twenty-four experimental rabbit models of acute PE were established through femoral vein using gelatin sponge as embolus materials, which were randomly divided into 4 groups. Plain and enhanced CT scans were performed before embolization and after embolization at 2h, 1d, 3d, 7d(i.e. group 1, 2, 3, and 4, n=6, respectively) to observe the dynamic changes of PE. Rabbits were killed to analyze the pathologic basis of the corresponding changes. Comparing to pathology as a standard of reference, CT numbers of the embolic areas and normal pulmonary parenchyma were measured in the standard non-enhanced and enhanced CT, respectively. Paired student t test was used to compare changes of CT values. Results: The CT findings of PE at 2h after embolization reveals areas of decreased attenuation(6/6). CT revealed pulmonary oligemia(4/6), mosaic signs associated with crescent-shaped shadow of pleura(1/6) at 1 day after embolization, and 1 rabbit showed normal. Lung consolidation was displayed in 4 rabbits after 3 days, 1 rabbit showed mosaic sign, 1 rabbit showed ground-glass change. Consolidation and infarction were displayed in 4 rabbits after 7 day, accompanied by pleural effusion, pleura thickening and lung bullae; 1 rabbit displayed pulmonary oligemia, 1 rabbit showed local pleural thickening and small amount of pleural effusion. On unenhanced CT scans, there was no significant difference between pre-embolism and post-embolism of embolic areas of the 2h and the 1 day group(P>0.05). There were significant differences of CT values and net increased CT values between preembolism and postembolism of the embolic areas(P<0.01) after 2h and 1 day. After embolism, there was no significant difference on CT values of 2h and 1 day groups between embolism areas and normal pulmonary parenchyma(P>0.05). On enhanced CT scans, there was significant difference for CT values and net increased CT values between embolic areas and normal pulmonary parenchyma(P<0.01) after 2h, 1 day; but there was no significant difference of CT values of unenhanced and enhanced of 3 day and 7 day groups respectively(P>0.05). Conclusion: The pulmonary embolism models was established by using gelatin sponge as embolus. CT, especially enhanced CT can depict the dynamic changes of the PE from pulmonary oligemia to consolidation and infarction, which were correlated well with pathologic findings.

DOI:
Objective: To study the safety and effect of endovascular therapy of long-segment total occlusion of superficial femoral artery using femoropopliteal artery dual input technique. Materials and Methods: Fifteen patients were treated with endovascular therapy of long-segment total occlusion of superficial femoral artery using femoropopliteal artery dual input technique. CTA examination of lower limb were performed for all patients which can be evaluated the length of occlusion segment and distal outflow tract. All patients underwent retrograde popliteal artery puncture and the balloon angioplasty and the stent implantation were performed in all cases. The ankle/braehial index(ABI) and symptoms post-treatment and pre-treatment were analyzed. Ankle-brachial index and Doppler ultrasound of lower extremity arteries were peformed every 3 months after endovascular therapy. Results: Fifteen cases with long-segment total occlusion of superficial femoral artery were recallalized, with technical success rate of 100%. The symptoms of rest pain disappeared in 14 cases． The ABI was 0.68±0.088 for post-treatment and 0.36±0.12 for pre-treatment respectively(t=18．62, P<0.01)． During 2～16 months’ follow up, 1 case of foot ulcers has not been controled, undergoing amputation 2 months after interventional treatment; 1 case recurrence of rest pain 3 months after therapy, Doppler ultrasound showing femoral artery stent restenosis, which was treated successfully once again after balloon angioplasty. The remaining patients with no recurrence. Conclusion: It is safe and effective to apply femoral artery combined with popliteal artery puncture technique to treat long-segment total occlusion of superficial femoral artery. It is a new idea for interventional treatment of lower extremity arterial occlusion.
