Uterine Leiomyosarcoma: Can MRI Differentiate Leiomyosarcoma From Benign Leiomyoma Before Treatment?

Objective: The purpose of this article is to provide background on the epidemiologic, clinical, and economic impact of uterine leiomyomas, summarize the concerns associated with treating women with potential occult leiomyosarcomas (LMSs), and review the known and emerging imaging features of typical and atypical leiomyomas and explain how to differentiate them from LMSs.

Conclusion: Surgical management of presumed benign uterine leiomyomas received popular media attention when a case of disseminated LMS occurred after laparoscopic power morcellator-assisted hysterectomy. A subsequent U.

Utility of MR Angiography in the Identification of Prostatic Artery Origin Prior to Prostatic Artery Embolization.

In 17 patients who underwent prostate artery embolization for treatment of lower urinary tract symptoms, the accuracy of preprocedural magnetic resonance (MR) angiography was retrospectively compared with intraprocedural digital subtraction angiography (DSA) in the identification of prostatic artery origin. Of 34 vessels, 26 MR angiography identified origins (76.5%) were confirmed by DSA at the time of embolization.

MRI features of primary rare malignancies of the liver: A report from four university centres.

Purpose: To determine if rare primary malignancies of the liver may have consistent features on magnetic resonance imaging (MRI).

Materials And Methods: This IRB-compliant retrospective study reviewed the records from the pathology departments of four university centres over an 11-year period from 2005-2016 to identify rare primary malignant tumours, which were cross-referenced with MRI records. MRI studies of these patients were reviewed to determine if these tumours exhibited consistent and distinctive features.

Short-term imaging response after drug-eluting embolic trans-arterial chemoembolization delivered with the Surefire Infusion System® for the treatment of hepatocellular carcinoma.

Purpose: To review the initial imaging responses after drug-eluting embolic trans-arterial chemoembolization (DEE-TACE) delivered with the Surefire Infusion System ® for the treatment of hepatocellular carcinoma (HCC).

Methods: Single center retrospective evaluation of patients who underwent DEE-TACE for HCC, delivered with SIS. Information was gathered from available medical records.

Magnetic resonance imaging of acute appendicitis in pregnancy: a 5-year multiinstitutional study.

Objective: The purpose of this study was to determine the diagnostic performance of magnetic resonance imaging (MRI) in the diagnosis of acute appendicitis during pregnancy in a multiinstitutional study.

Study Design: In this multicenter retrospective study, the cases of pregnant women who underwent MRI evaluation of abdominal or pelvic pain and who had clinical suspicion of acute appendicitis between June 1, 2009, and July 31, 2014, were reviewed. All MRI examinations with positive findings for acute appendicitis were confirmed with surgical pathologic information.
