Unexpected Finding on Mammography and MRI due to Accumulation of Iron Oxide Particles Used for Sentinel Lymph Node Detection.

We present a case with imaging artefacts on mammography and Magnetic Resonance Imaging (MRI) caused by iron oxide particles. After being diagnosed with the medullary cancer of the breast, the female patient had a breast conserving surgery on right breast. Iron oxide particles were used for the detection of the sentinel lymph node during operation.

Vacuum-assisted stereotactic biopsy for isolated BI-RADS 4 microcalcifications: evaluation with histopathology and midterm follow-up results.

Purpose: The aim of this study was to evaluate the 10-gauge vacuum-assisted stereotactic biopsy (VASB) of isolated Breast Imaging Reporting and Data System (BI-RADS) 4 microcalcifications, using histology and follow-up results.

Methods: From January 2011 to June 2013, VASB was performed on 132 lesions, and 66 microcalcification-only lesions of BI-RADS 4 were included into our study. VASB was performed using lateral decubitis stereotaxy for all patients.

Do Nuss bars compromise the blood flow of the internal mammary arteries?

Objectives: Minimally invasive repair of pectus excavatum, the so-called Nuss procedure, has become a popular technique in recent years. The internal mammary arteries (IMAs) lie on the posterolateral surface of the sternum, and the Nuss bar is likely to obstruct the blood flow in these arteries. This obstruction could become important in the later stages of the lives of these young people if they were to require coronary artery bypass grafting.

MRI in stress urinary incontinence: endovaginal MRI with an intracavitary coil and dynamic pelvic MRI.

Purpose: To evaluate both morphology of the urethra and its supporting structures using endovaginal magnetic resonance imaging (EV-MRI) and the grade of the bladder neck prolapsus using dynamic pelvic MRI (DP-MRI) in women with stress urinary incontinence (SUI).

Materials And Methods: We compared 25 women with SUI and 8 controls according to the different layers of the urethra, the degree of distortion in the periurethral, paraurethral, and pubourethral ligaments, the vesicourethral angle, the retropubic space, and the thickness of the puborectal muscle. The SUI group was also evaluated according to the number of deliveries and degree of the bladder neck prolapsus.

Non-invasive evaluation of the coronary venous system in patients with chronic systolic heart failure by 64-detector computed tomography.

Background: Imaging coronary venous systems to guide transcatheter cardiac interventions are becoming increasingly important, particularly in heart failure patients who are selected for cardiac resynchronization therapy (CRT). Failure of left ventricular (LV) lead placement during the procedure has been attributed to the inability to insert catheters into the coronary sinus and the lack of suitable side branches.

Purpose: To comparatively assess the value of a 64-detector MDCT examination in visualizing the cardiac veins and evaluating the morphological characteristics of the coronary venous system in patients with and without chronic systolic heart failure (SHF).

Comparison of power Doppler ultrasound with gray scale transrectal ultrasound in predicting cancer positive prostate biopsy cores.

Objective: The aim of this study is to compare the effect of transrectal power Doppler ultrasound (PDUS) and gray scale transrectal ultrasound (TRUS) for the diagnosis of prostate cancer.

Materials And Methods: Seventy-six patients evaluated with transrectal PDUS and TRUS underwent eight systematic TRUS guided core-needle biopsies, with additional cores from abnormal areas. Histologic diagnoses were classified as benign prostatic hyperplasia, chronic prostatitis, intraepithelial neoplasia and adenocarcinoma.

Degeneration of the lumbar spine and dual-energy X-ray absorptiometry measurements in patients without osteoporosis.

Aim: The aim of this study was to evaluate the effects of degenerative findings on the accuracy of readings obtained by dual-energy X-ray absorptiometry (DXA) in patients without osteoporosis.

Methods: Twenty-four female patients who had undergone both DXA and lumbar magnetic resonance imaging were included in the study.

Conclusion: This study has demonstrated that degenerative radiologic changes, especially in the osteophyte area, affect bone mineral density measurements, so degeneration should be considered in the evaluation of this measurement.

Normal magnetic resonance contrast enhancement of extraocular muscles: a quantitative analysis.

The purpose was to evaluate quantitatively the magnetic resonance contrast enhancement of normal extraocular muscles and the use of temporal muscles as a reference of enhancement. Eighty extraocular and 20 temporal muscles were taken into analysis. Before contrast administration, mean intensity of extraocular muscles was found to be higher than that of temporal muscles (p < 0.
