MR findings of ruptured endometrial cyst: comparison with tubo-ovarian abscess.

Objective: To evaluate the MR findings of ruptured endometrial cyst, focusing on the differentiation from tubo-ovarian abscess (TOA).

Patients And Methods: We reviewed the records of 21 patients who underwent preoperative MR examinations for TOAs (n=15) or ruptured endometrial cysts (n=6). We evaluated the presence of hyper-intense ascites and hyper-intense peritoneum in T1-weighted sequences, strong enhancement of the peritoneum, hyper-intense content and hyper-intense rim of the ovarian lesion in T1-weighted sequences, and strong wall enhancement of the ovarian lesion.

Soft-tissue perineurioma of the retroperitoneum in a 63-year-old man, computed tomography and magnetic resonance imaging findings: a case report.

Introduction: Soft-tissue perineuriomas are rare benign peripheral nerve sheath tumors in the subcutis of the extremities and the trunks of young patients. To our knowledge, this the first presentation of the computed tomography and magnetic resonance imaging of a soft-tissue perineurioma in the retroperitoneum with pathologic correlation.

Case Presentation: A 63-year-old Japanese man was referred for assessment of high blood pressure.

Differentiation between hepatic haemangiomas and cysts with an inversion recovery single-shot turbo spin-echo (SSTSE) sequence using the TI nulling value of hepatic haemangioma with sensitivity encoding.

Objective: To evaluate the additional value of inversion recovery (IR) single-shot turbo spin-echo (SSTSE) imaging with sensitivity encoding (SENSE) using the inversion time (TI) value of hepatic haemangioma as a supplement to conventional T2-weighted turbo spin-echo (TSE) imaging for the discrimination of hepatic haemangiomas and cysts.

Methods: A total of 134 lesions (77 hepatic haemangiomas, 57 hepatic cysts) in 59 patients were evaluated. Three readers evaluated these images and used a five-point scale to evaluate the lesion status.

Simple new technique for sonographic measurement of the thyroid in neonates and small children.

Purpose: The aim of this study was to determine whether the ratio of the thyroid width (Th) to the trachea width (Tr) is a useful technique for sonographic estimation of thyroid size in neonates and small children.

Methods: We prospectively performed sonographic examination of the thyroid gland in 30 pediatric subjects ranging in age from 1 week to 12 years. The sum of the maximum width of the left thyroid lobe and the maximum width of the right lobe was considered the Th.
