TANG Le-mei;SONG Qing-wei;LANG Zhi-jin;YANG Zhi-hong
DOI:
Objective: To discuss the value of susceptibility-weighted imaging(SWI) in the cerebral vascular malformations and the features of SWI. Materials and Methods: Forty-one patients(with cerebral vascular malformations including 23 cases of cavernous angioma, 13 cases of arterio-venous malformation, 5 cases of venous malformation) were examined with MR scanner. The sequences included SWI, T1WI, T2WI and post-contrast T1WI. The comparison of SWI and conventional MR sequences was done according to surgical findings and the imaging of DSA, then discuss the value of SWI in the diagnosis of cerebral vascular malformations. Results: SWI showed more lesions of cavernous angioma than conventional sequences, and SWI detected 3 cases of wide spread hemangiomas and 5 cases with multiple nidi. SWI displayed the same lesion larger than the conventional sequences. Five cases of venous malformation, 6 lesions are shown by SWI, and 5 shown by conventional sequences, and the medullary veins showed clearly, according to the post-contrast T1WI; SWI revealed 13 feeding arteries and 18 draining veins, and the conventional sequences showed the same number of feeding arteries and 13 draining veins. Conclusion: SWI is the best sensitive sequence for detecting cerebral vascular malformation, and the ideal method to screen the cerebral vascular malformations, it will provide more complete and detailed information combining with other sequences.

DOI:
Objective: To explore the value of susceptibility weighted imaging(SWI) in the diagnosis of cerebral venous/venous sinus thrombosis combined with venous hemorrhagic cerebral infarction（CVST-VHCI）. Methods: The imaging data of the 18 patients with CVST-VHCI proved by DSA or pathology were studied retrospectively on GE 3.0T MR system, and were compared with those of 12 patients with simple cerebral hemorrhage and 8 patients with brain tumor which located in nearly the same region. Result: In the 18 patients with CVST-VHCI, SWI showed patches of hypo-signal intensity in parietal cortex or parietal subcortex. There were wide spread or earthworm-like mesh cortex veins or pulp veins around the cortex or parietal subcortex. In the 12 patients with simple cerebral hemorrhage, SWI revealed lesions of low signal intensity. The cortex veins were normal or reduced slightly. In the 8 patients with brain tumor, SWI expressed clumping mixed-signal and linear hypo-signal small veins and patchy hypo-signal hemorrhage inside the tumor. Conclusion: For the hemorrhagic disease in parietal cortex or parietal subcortex, SWI can reveal the specific feature by showing expanded cortex vein or medullary vein to improve the diagnosis of CVST-VHCI. So SWI is an important supplement of cMRI and MRV.

DOI:
Objective: To investigate MSCT manifestations after the healing of active pulmonary tuberculosis, and estimate the value of CT in detecting prognosis and follow-up of pulmonary tuberculosis. Material and Methods: Sixty bacteriologically-cured patients with smear-positive pulmonary tuberculosis were included in this study, whose CT manifestations of pre-treatment, post-treatment and 6 months follow-up were observed. CT images were also acquired at the end of expiration. The small airway obstruction and air trapping signs were observed, and explored the correlation between the air trapping volume and pulmonary function parameters. Results: In pre-treatment, post-treatment and 6 months follow-up, the detection rate of activity signs in CT was 95.0%, 31.7% and 1.7%, respectively. The accuracy of CT diagnosing the activity of pulmonary tuberculosis was 95.0%, 68.3% and 96.7% in pre-treatment, post-treatment and 6 months follow-up respectively. The residual lesions were found to be reduced in size and absorbed after drug withdrawal for 6 months in 39 cases(76.5%). Small airway lesions still existed after treatment. The air trapping volume had an obvious correlation with FEF50% and MMEF(χ2=10.48, P<0.01). Conclusions: The CT manifestations of prognosis are demonstrated later than bacteriology. There is a limitation in assessing the activity of pulmonary tuberculosis only by CT signs. CT plays a role in demonstration of secondary small airway changes after bacteriologically cured.

CHEN Jun;YAN Ping;ZHANG Bo;WU Tao
DOI:
Objective: To evaluate the diagnostic value of contrast-enhanced ultrasound in the diagnosis of breast lesions. Methods: Sixty-two cases of breast lesions, in which 33 cases were benign, and 29 were malignant, were examined with contrast-enhanced ultrasound. The enhancement pattern, time-intensity curve and contrast parameters were analyzed to compare the differences between benign and malignant lesions. Results: Significant differences were found in homogeneity of the intensity, the initial enhancement time, peak time and the slope rate(all P<0.05). No significant difference were found in peak intensity, average intensity and areas under peak～60s of the time-intensity curves. The inhomogenity of the intensity, the time from initial enhancement<10s, peak time <20s and the slope rate<5 were set as the indicators for malignancy. The diagnostic accuracy of B-ultrasound and color Doppler flow imaging is 88.7%, when combined with contrast-enhanced ultrasound, the diagnostic value can be improved to 93.6%. Conclusions: Contrast-enhanced ultrasound can improve the accuracy of diagnosis for breast lesions.

FANG Ting-song;XU Yi-kai;PENG Jia-you;FAN Chang-shu
DOI:
Objective: To discuss the imaging findings of synovial sarcoma of extremities and evaluate the value of X-ray, CT, MRI and DSA. Methods: Imaging data of 13 cases of synovial sarcoma of extremities confirmed pathologically was analyzed retrospectively. Results: Most synovial sarcomas located in the extremities close to joints. Synovial sarcomas detected by radiography typically appeared as round, oval or multilobulated juxtaarticular soft-tissue masses with calcification in some cases. The most common CT appearance of synovial sarcoma was heterogeneous deep-seated soft-tissue mass with attenuation similar to or slightly lower than that of muscle. On T1WI, synovial sarcomas typically appeared as prominently heterogeneous multilobulated soft tissue masses with signal intensity similar to or slightly higher than that of muscle. On T2WI, synovial sarcomas appeared as prominent heterogeneity with predominantly high signal intensity. Angiogram showed dense tumor staining and neovascularity. Conclusion: Synovial sarcoma has some specific image features. Comprehensive analysis of multiple imaging examinations and clinical features are helpful for the diagnosis of synovial sarcoma.

DOI:
Objective: To explore the imaging features of chondromyxoid fibroma of bone and evaluate their clinical value. Methods: Eleven cases with chondromyxoid fibroma of bone confirmed by surgical pathology underwent radiography, CT plain scanning and MR SE-T1WI, SE-T2WI and SE-T1WI enhanced scanning before operation, the imaging data was reviewed and analysed retrospectively in comparison with surgical and pathological results. Results: The lesions in seven cases of 11 chondromyxoid fibroma with well defined osteolytic destruction were located at the metaphysis of the long tubular bone, in 2 cases the lesion was in pelvis, 1 case in skull, the other case in vertebrae. The diameter of the tumor ranged from 3.2cm to 16.9cm, with a mean diameter of 4.7cm. When located in a long tubular bone, chondromyxoid fibroma were generally eccentrically situated at the metaphysis, radiolucent and elongated in shape, cortical expansion, exuberant endosteal sclerosis, and coarse trabeculation, with small area of ring- and arc-like calcification, thin sclerotic rim separated the tumor from adjacent normal bone, there may be little periosteal reaction and small soft tissue masses. The CT value was similar to muscle and CT is optimal to detect the matrix mineralization. MR imaging depicted low signal intensity with well defined rim on T1WI, high signal intensity on T2WI. Conclusion: The imaging manifestations of chondromyxoid fibroma were specific to some extent. Combined utilization of plain X-ray, CT, and MRI is helpful for the diagnosis and differential diagnosis of chondromyxoid fibroma.
