ABSTRACT
Objective To assess the effect of magnetic resonance imaging (MRI) on preoperative staging of endometrial carcinoma and depth of myometrial invasion. Methods Fifty-six patients with endometrial carcinoma were underwent conventional and contrast-enhanced MR scan. The results of pathology , MRI examinations of preoperative staging and depth of myometrial invasion were assessed and compared. Results The accurate rate of MRI diagnosis in preoperative staging diagnosis was 82.1% (46/56) and the consistency check as Kappa was 0.771 (P < 0.001). Conclusions MRI may be a good diagnostic tool with high sensitivity and specificity for assessing myometrial invasion and detecting tumour extension and should be considered as a routine part of the preoperative assessment in all patients with endometrial carcinoma.
ABSTRACT
Objective To evaluate the value of diffusion-weighted MRI ,time of flight MR angiography (TOF-MRA) and 3D dynamic contrast enhanced MR angiography (3D DCE-MRA) in the diagnosis of transient ischemic attacks(TIA). Methods 176 consecutive patients with TIA were undergone MRI, including FLAIR,DWI,TOF-MRA and 3D CE-MRA sequences. Results Of 176 cases,48.9% of patients were found having hyperacute ischemic lesions by DWI sequence and 18.2% of lesions could be detected by T2WI.TOF-MRA showed arterial stenosis and occlusion in 76 cases(43.2%),false positive rate and excessive diagnosis were happened in 20 cases.3D CE-MRA of brain showed arterial stenosis and occlusion in 69 cases(39.2%).3 cases with aneurysm and 2 cases with arteriovenous malformation were detected by two methods.3D CE-MRA of neck showed arterial stenosis and occlusion in 38 cases(21.6%).Conclusion DWI and MRA are helpful in detecting the hyperacute ischemic lesion and evaluating the arterial lesions in the patients with TIA.
