Diagnostic accuracy of segmental enhancement inversion for diagnosis of renal oncocytoma at biphasic contrast enhanced CT: systematic review.

Objectives: To use systematic review to evaluate the diagnostic accuracy of segmental enhancement inversion (SEI) at contrast-enhanced biphasic multi-detector computed tomography (MDCT) for the diagnosis of renal oncocytoma.

Methods: Several electronic databases were searched through October 2013. Two reviewers independently selected studies that met the inclusion criteria and extracted data.

Multi-echo gradient recalled echo imaging of the pelvis for improved depiction of brachytherapy seeds and fiducial markers facilitating radiotherapy planning and treatment of prostatic carcinoma.

Purpose: MR localization of implanted devices for radiotherapy (RT) in prostatic carcinoma is critical for treatment planning. This clinical note studies the application of a multi-echo gradient recalled echo (GRE) pulse sequence with sum of squares echo combination (ME GRE) to enhance detection of seeds and fiducials.

Materials And Methods: Fifteen patients who underwent MRI using fast spin echo (FSE), single-echo and ME GRE over a 9-month period were retrospectively evaluated by two readers who assessed overall image quality, depiction of seeds/fiducials and image sharpness using a 5-point scale (1 = poor, 2 = suboptimal, 3 = adequate, 4 = above average, 5 = excellent).

Computed tomographic findings of radiation-induced acute adrenal injury with associated radiation nephropathy: a case report.

Radiation nephropathy was first recognized in 1906. The kidney is a radiosensitive organ with a tolerance dose (5% complications in 5 years) of 20 Gray. The imaging findings of acute and chronic radiation induced renal injury are previously described.

Multi-modality organ-based approach to expected imaging findings, complications and recurrent tumour in the genitourinary tract after radiotherapy.

Purpose: Radiotherapy (RT) is an integral component in the management of many abdominal and pelvic malignancies. Imaging follow-up in patients who have received RT is performed to assess for treatment response, evaluate for tumour recurrence and to diagnose complications related to treatment. The purpose of this pictorial review is to depict the expected imaging findings and potential complications following RT in the genitourinary (GU) tract using an organ-based approach and to review the diagnosis of locally recurrent tumour in the GU tract following RT.

Parenteral ferumoxytol interaction with magnetic resonance imaging: a case report, review of the literature and advisory warning.

Background: Ferumoxytol is a safe and effective parenteral therapy used for the treatment of iron deficiency anaemia that has recently been approved for use in North America and in Europe.

Methods: Ferumoxytol consists of a superparamagnetic iron oxide (SPIO) core, which causes T1, T2 and T2* shortening effects, and a carbohydrate shell, which results in a prolonged intravascular half life.

Results: These properties are under-reported and not well recognised.

Triphasic CT in the diagnosis of acute mesenteric ischaemia.

Objective: To evaluate the yield of each phase in a triphasic CT protocol used to diagnose acute mesenteric ischaemia (AMI).

Methods: Retrospective analysis of patients who underwent CT to exclude AMI was conducted. From 218 patients, 80 were randomly selected for analysis: 39 with proven AMI; 41 controls.

Recording blood pressure readings in elderly patients' charts: what patient and physician characteristics make it more likely?

Objective: To identify patient and physician characteristics associated with family physicians recording blood pressure (BP) measurements in the medical charts of their elderly patients.

Design: Retrospective review of patients' charts during a 12-month period and baseline questionnaire on the sociodemographic and practice characteristics of family physicians participating in the Community Hypertension Assessment Trial. The chart review collected data on patients' demographics, cardiovascular risk factors, antihypertensive medications, number of visits to family physicians, and number of BP readings recorded.
