DOI:
Objective: To analyse the MRI appearances of adenolymphoma in parotid gland, and improve the accuracy of diagnosis. Materials and Methods: The clinical and MRI findings of 40 cases with adenolymphoma in parotid gland were retrospectively analyzed. Among the 40 cases, the ratio of male to female was about 4.7∶1(33∶7), and the age ranged from 19 to 82 years old(mean age 58 years old), 31 cases of adenolymphoma(31/40, 77.5%) were over 50 years old, and 33 cases(33/40, 82.5%) had smoking habit. Results: Among the 40 cases, altogether there were 62 lesions, with solitary lesions(n=29), multiple lesions(n=11), most adenolymphomas(46/62, 74.2%) located in the posterior and inferior quadrant. On MRI, lesions were round, oval or lobulated in shape, well-defined, hypointense on T1WI, iso- or hyterintense on T2WI, cystic area showed long T1, long T2 signal, most of the lesion showed early mild or moderate enhancement after contrast administration. Conclusion: Adenolymphoma of parotid gland have some characteristic features on clinical and imaging, before operation, MRI not only can well demonstrate the size, number and location of adenolymphoma, but also can help diagnosis, differentiation diagnosis and therapeutic decision.

SUN Ji-lin;ZHANG Ping;ZHAO Wen-qing;WU Jie;LI Su-min
DOI:
Objective: To evaluate the value in localizing the epileptic focus by magnetic source imaging(MSI) in patients with cavernous angioma(CA) and seizure. Methods: MRI and MSI examination were proceeded in 13 patients with CA and had epilepsy. To observe the relationship of epileptic focus determined by MSI with the location of the CA, all of the 13 patients were operated on. Results: The distance of the location between the epileptic focus identified by MSI and the CA was less than 2cm in 11 cases and more than 2cm in 2 cases. According to Engel classification of epilepsy, all the patients achieved Engel Class 1 outcomes. In 12 cases was seizure free for 6~53 months after operation. One patient had only 1 seizure episode after operation. Conclusion: MSI could define the relationship between the epileptic focus and the location of the CA. The results of MSI have much value to make the surgical plan before operation.

DOI:
Objective: To estimate the individual absorbed dose to the parotid and submandibular glands in patients with differentiated thyroid carcinoma(DTC) receiving 131I ablative therapy. Methods: Forty patients, including 7 male, 33 female, aged from 17~63(44±15)years, with DTC after thyroidectomy were prospectively recruited in this study. Head-neck anterior and posterior static scintigrams were obtained at 1, 2, 3, 4, 12, 24, 48h after administration of 3.7GBq radioiodine. Manually drawn regions of interest of the parotid and submandibular glands were used to determine the activities arising from salivary glands after background correction. The cumulative activites of salivary glands were computed via area under time-activity curves by Origin 7.0 software. According to MIRD methods, absorbed dose of salivary glands was calculated. Results: The mean absorbed dose to parotid and submandibular gland was (0.15±0.10)mGy/MBq, (0.19±0.07)mGy/MBq, respectively. Conclusion: Radiation dose to the salivary glands of DTC patients receiving 131I abaltive therapy is low.

DOI:
Objective: To study the size and shape of pulmonary vein(PV) ostia, its distance to the first bifurcation, and the variation of PV trunk as it approaches the left atrium. Methods: The data of 103 patients were collected in this study. Pulmonary venous drainage patterns to the left atrium were analysed. The caliber of PV and distance to the first bifurcation were measured, and venous ostial index(VOI) were calculated. Results: Most patients(n=81, 78.6%) had four standard PVs. The caliber of superior PV ostia was larger than that of the inferior PV ostia. The right superior and inferior PV ostia were larger than the left PV ostia respectively(P<0.05). The VOI of the right was larger than that of the left. The caliber of PV in men was larger than that in women(P<0.05). The VOI between men and women was similar(P>0.05). The distance to the first bifurcation of each PV varied. They were different between the left and the right, the superior and the inferior PV(P<0.05). The PV ostial branches emergence rate of the right inferior PV(74.7%) was the highest and that of the left superior PV(3.2%) was the lowest. The caliber of some left inferior PV(55.6%) gradually decreased and the others increased as they entered the left atrium. All of the PV shapes gradually became oval. Conclusion: The PVs have a great anatomic variations. There is significant variability in PV caliber, shape and ostial branches emergence rate. Particular care must be taken when the left inferior PV is evaluated for its stenosis, as it usually narrows as it enters the left atrium.

DOI:
Objective: To evaluate the clinical value of dual energy bone removal CT angiography(DE-CTA) for the diagnosis of intracranial internal carotid artery aneurysms. Materials and Methods: Twenty-four patients underwent DE-CTA and DSA between Jun. 2008 and Dec. 2008. Image post-processing of DE-CTA and routine CTA was performed using the dedicated software. Two well-experienced radiologists evaluated image quality of DE-CTA and presence of aneurysms, number, aneurysm neck and maximal dimension were recorded. Comparable study was performed with DSA, the gold standard. Results: Four vessels were non-evaluable because of occlusion(n=2) and poor image quality resulting from imperfect delayed time(n=2); while the remaining 44 vessels had evaluable image quality. With DSA as the reference of standard, routine CTA and DE-CTA detected 23 and 26 aneurysms, respectively, corresponding to sensitivities of 88.5% and 100%. Mean and maximal diameter of aneurysm neck were (3.5±1.3)mm and (6.7±5.1)mm, with a good correlation with DSA[aneurysm neck, (3.4±1.3)mm; maximal diameter, (6.9±5.2)mm]; (r=0.565, P=0.015; r=0.979, P=0.000). Conclusions: DE-CTA can remove bone in the skull base and visualize the intracranial internal carotid artery with a high diagnostic sensitivity for detection of intracranial aneurysms of internal carotid artery. The technique of DE-CTA should be widely used in the routine clinical practice.

ZHANG Si-wei;WANG Yi-ming;YOU Yu-mei
DOI:
Objective: To evaluate the effects of different subtypes of idiopathic hypercalciuria(IH) on bone metabolism. Methods: Using dual-energy X-ray absorptiometry, bone mineral density(BMD) in lumbar spine and left femur were measured in 72 patients with IH and 72 age, sex and body weight index matched healthy persons. Biochemical markers of bone metabolism were also measured in all subjects. Results: In comparison to the control group, the patients with IH had significantly higher urinary Ca/Cr and DPD/Cr levels(P<0.01), and serum BALP, PTH and BGP levels were significantly higher in renal IH patients(P<0.05), whereas there was no significant difference between absorptive IH group and control group in serum BALP, PTH and BGP levels. Renal IH patients had significantly lower femoral neck BMD and lumbar spine BMD values when compared with control subjects. There was a significant negative correlation between BMD in different sites and the serum BALP, BGP and urinary DPD levels. Conclusion: Patients with renal lithiasis should be evaluated for IH. Osteopenia and disorder of bone metabolism are common in patients with IH, and monitoring the BMD and biochemical markers of bone is beneficial to early detection of such abnormalities for those patients.

LI Shu;ZHANG Li-na;WANG Xin;LIU Ting;LI Pei-ling;XIE Xiu-li;XU Ke
DOI:
Objective: To improve the understanding concerning CT initial manifestations and changing course of invasive pulmonary aspergillosis(IPA). Methods: One hundred and forty-one serial CT scans(mean, 6.4) in 22 consecutive patients were reviewed retrospectively over a median follow-up of 96 days(20~692 days), number and size of lesions and CT manifestations of IPA were evaluated dynamically. Results: On CT initial imaging, multiple lesions usually were observed, median lesion number and size were 5.3(1~20) and 1.39cm(0.3~3.7cm) respectively. An accompanying halo sign was early characteristic CT signs of IPA and was observed in 77.3%(17/22) patients at the initial CT scans. During 7~14 days follow-up, both number and size of lesions showed increase, 5.8(1~23) and 1.64cm(0.4~4.2cm) respectively. The strongest predictive diagnosis of IPA was the formation of the air crescent sign and cavitation that evolved at a median 23 days. Conclusion: IPA mostly occurred in immunocompromised patients, An accompanying halo sign around nodes was early characteristic CT signs of IPA, familiar with its CT manifestations and changing course have an important significance in diagnosis and estimating prognosis.

DOI:
Objective: To investigate the MDCT imaging manifestations and pathological basis of bowel wall thickening due to nontumorous causes. Methods: MDCT findings of 284 patients with bowel wall thickening due to nontumorous causes confirmed by surgery, biopsy or clinical follow-up were studied retrospectively, paying attention to location, range, symmetric or asymmetric, involvement degree of thickening, attenuation, presence or absence of enhancement and associated perienteric abnormalities of thickened bowel wall. MDCT findings were analyzed with correlation with pathological changes. Results: All the non-tumorous disease caused bowel wall thickening included liver cirrhosis(109 cases) , acute pancreatitis(54 cases), bowel obstruction(36 cases), inflammatory bowel disease(14 cases), ischemic bowel disease(12 cases), radiation enterocolitis(13 cases), tuberculosis (12 cases), immune reaction(10 cases), infective enteritis(3 cases), acute appendicitis(3 cases), hypoproteinemia(5 cases), rare diseases(8 cases) and normal variants(5 cases). The attenuation pattern of the thickened bowel wall included high attenuation(1 case), iso-attenuation(144 cases), low attenuation(127 cases), fat deposition(5 cases) and pneumatosis(7 cases). The enhancement pattern of the thickened bowel wall included mild enhancement(249 cases), marked enhancement(32 cases) and unenhancement(3 cases). Degree of bowel wall thickening included mild thickening(279 cases) and marked thickening(5 cases). Two hundred and twelve patients with bowel wall thickening showed multisegmental distribution while 72 patients had single segmental involvement. Associated perienteric abnormalities of thickened bowel wall included swelling of fat(218 cases), ascites(189 cases), lymphadenopathy(5 cases), perienteirc abscess(2 cases), mesenteric vascular lesion(25 cases) and involvement of solid abdominal organs(169 cases). Conclusion: Bowel wall thickening due to nontumorous causes showed mild and homogeneous thickening, iso-attenuation or low attenuation, mild enhancement and multisegmental distribution on MDCT. Paying attention to the characteristics and pathological basis of thickening of bowel wall benefits the diagnosis and differential diagnosis of various intestinal diseases.
