The aim of this study was to detect coronary artery disease using 99m Tc MIBI myocardial perfusion imaging in patients with valvular disease. [WT5”BX]Methods.[WT5”BZ] Thirty patients with valvular disease confirmed by echocardiography underwent 99m Tc MIBI myocardial perfusion imaging using multiSPECT 1h after stress test (exercise, dipyridamole or dobutamine test) and were performed coronary angiography within 1 month before valvular operation. [WT5”BX]Results.[WT5”BZ]For 29 out of the 30 patients, the results of 99m Tc MIBI myocardial perfusion imaging were similar with those of coronary angiography, the concordance rate was 96 7% and the negative predictability was 100%. [WT5”BX]Conclusion.[WT5”BZ] 99m Tc MIBI myocardial perfusion imaging is a reliable non invasive method for detecting coronary artery disease in patients with valvular disease and so as to draw up suitable operation programs for them. 展开更多

It is well known that angiogenesis is critical in the transition from premalignant to malignant lesions.Consequently,early detection and diagnosis based on morphological changes to the microvessels are crucial.In the last few years,new imaging techniques which utilize the properties of light-tissue interaction have been developed to increase early diagnosis of gastrointestinal(GI) tract neoplasia.We analyzed several "red-flag" endoscopic techniques used to enhance visualization of the vascular pattern of preneoplastic and neoplastic lesions(e.g.trimodal imaging including autofluorescence imaging,magnifying endoscopy and narrow band imaging).These new endoscopic techniques provide better visualization of mucosal microsurface structure and microvascular architecture and may enhance the diagnosis and characterization of mucosal lesions in the GI tract.In the near future,it is expected that trimodal imaging endoscopy will be practiced as a standard endoscopy technique as it is quick,safe and accurate for making a precise diagnosis of gastrointestinal pathology,with an emphasis on the diagnosis of early GI tract cancers.Further large-scale randomized controlled trials comparing these modalities in different patient subpopulations are warranted before their endorsement in the routine practice of GI endoscopy. 展开更多

Objective: To investigate the role of MRI in the diagnosis of intracranial germinoma. Methods: MRI features of 19 cases of intracranial germinoma confirmed by operations and pathological findings were analyzed retrospectively. Results: Germinomas were found in the sellar region in 10 patients (including 5 males and 5 females), in the pineal region in 6 and in the thalamus and basal ganglia in 3, the 9 patients in the latter 2 groups all being males. The characteristic MRI findings of intracranial germinomas were as follows: (1) Lesions were isointense or slightly hypointense on T1WI while isointense or slightly hyperintense on T2WI. The germinomas in the sellar region and pineal region showed no edema, but lesions in the thalamus basal ganglia showed mild to moderate edema and space-occupying effects. (2) Homogeneous or inhomogeneous Gd-DTPA enhancement were seen in most of the tumors. Conclusion: Multiaxial imaging and Gd-DTPA enhancement in MRI are helpful in the diagnosis and differentiation of intracranial germinomas on the basis of the patient's gender, the location of the tumor and its imaging characteristics. 展开更多

Methods: MRI manifestations and etiology of forty-six patients with enlarged SOV were analyzed. Results: SOV enlargement was noted to occur in carotid-cavernous fistula, ophthalmic Graves'disease, Tolosa-Hunt syndrome, inflammation at the apex of the orbit, orbital pseudotumor and thrombosis of cavernous sinus. The dilated vein appeared as signal void tubular shadows on both T1 and T2 weighted images. The diameter of the enlarged vein was 3.5-6.0 mm. Extraocular muscle enlargement, orbital pathologies, enlarged carotid cavernous sinus etc were also revealed by MRI. Conclusion: The dilated SOV may be well demonstrated by MRI. The etiological diagnosis of enlarged SOV can be made in combination with the associated findings. 展开更多
