ABSTRACT
<p><b>OBJECTIVE</b>To analyze the magnetic resonance imaging (MRI) features of endometrial carcinoma and their value in endometrial carcinoma staging according to the International Federation of Gynecology and Obstetrics (FIGO 2009) staging criteria.</p><p><b>METHODS</b>Fifty-four patients with pathologically confirmed endometrial carcinoma and complete clinical data underwent preoperative MRI examination. According to FIGO 2009 staging criteria of endometrial carcinoma, the MRI features of the tumor lesions were evaluated for assessment of myometrial invasion and cervical involvement and preoperative staging.</p><p><b>RESULTS</b>The 54 cases included 27 stage Ia cases, 9 stage Ib cases, 10 stage II cases, 5 stage III cases, and 3 stage IV cases. The total lesion display rate by MRI was 94% (51/54). With an isointensity or hypo-intensity on T1WI, the tumor lesions showed a moderate hyper-intensity on T2WI. In enhanced MRI scanning, the lesions showed a moderate heterogeneous enhancement, which had a lower intensity than the marked enhancement of the myometrium. Combination of T2WI and T1WI in fat suppression sequence enhanced scan had a diagnostic accuracy of 91% (49/54) for myometrial invasion, and the sensitivity, specificity and accuracy of MRI for detecting cervical involvement were 77%, 89%, and 83%, respectively. The accuracy of preoperative MRI-based staging of endometrial carcinoma was 89% (48/54), showing no significant difference from the results of postoperative FIGO 2009 staging and pathological examination (P>0.05).</p><p><b>CONCLUSION</b>MRI has a high accuracy in the diagnosis, evaluation of myometrial and cervical invasion depth, and preoperative staging of endometrial carcinoma, and serves as an important modality in assisting clinical decisions on the optimal therapeutic protocols and in prognostic estimation.</p>

Objective To review the experience and early clinical results of eversion carotid endartotectomy (eCEA) in treatment of patients with symptomatic carotid stenosis. Methods eCEA were performed on 32 patients who suffered from the extracranial carotid stonosis. The treatment results were retrospectively reviewed. Results Thirty-two patients were successfully treated with eCEA. The symptom in 17 patients with transient ischemia attach (TIA) admitted to hospital did not recurrence, the other original symptoms of the patients had different degrees of improvement or disappeared. Two patients had TIA during 72 h after surgery, but 24 h repeatedly CTA examination without infarcts oecurring, and recovered after the treatment of small doses of urokinase. Two cases of severe swelling appeared tracheal shift incision, and went smoothly through edema by treatment of tracheal intubatian. In 4 patients headache reliefed in 2-3 d after medical treatment of the dehydration. Seven patients appeared different degree of hoarseness, and got recovery through neurotrophic medication for 1 month. No other serious complication occurred. Follow-up by 6 months, no CTA carotid artery stenosis appeared again. Conclusion eCEA is an effective method to treat symptomatic carotid stenosis.
