MRI depicts small lesions, predicts malignancy in lung cancer

By Shalmali Pal

CT plays a major role in lung cancer imaging, with support from molecular imaging, sonography, and angiography. MRI also contributes to a greater understanding of small nodules, particularly with the recent introduction of improved protocols. Two new studies suggest that dynamic MRI and 3-tesla MRI can depict clinically significant small nodules, and also distinguish between benign and malignant lesions. In a related paper, Japanese nuclear medicine specialists looked at the value of MR for assessing cerebral lesions from metastatic lung cancer.

Computer-assisted MR guidance improves prostate biopsy

An automated prostate biopsy system based on real-time guidance with high-field MRI earned high scores for accuracy and image quality, according to German researchers. They found that using a transgluteal needle approach to the prostate with the patient prone was accurate and safe when used in combination with the pneumatically driven needle positioning system.

MR adds value to urodynamics for imaging stress urinary incontinence

By Shalmali Pal

The spectrum of abnormalities detected at MRI in women with stress urinary incontinence can be classified into two categories: findings related to urethral sphincter deficiency (ISD) and/or urethral hypermobility (UH). Researchers from Baltimore-based Johns Hopkins Medical Institutions assessed if MR findings could predict whether a patient had ISD or UH, and if those results could be correlated with urodynamics.

Noncontrast MR: The solution to the NSF problem?

By Sydney Schuster

Patients with renal insufficiency who undergo contrast-enhanced MR, and subsequently develop nephrogenic systemic fibrosis (NSF), represent a "malpractice pothole" for imaging experts. The obvious answer would be to swerve around the pothole and cease gadolinium use in these patients. But is that a realistic goal? Yes, if MRI vendors have their way, as they hustle to provide new and/or improved noncontrast imaging protocols. Meanwhile, MR experts weigh in on the pros and cons of going contrast-free.

Alliance for MRI gains delay, but new European rules still loom

By Brenda Tilke

A coalition of European MRI advocates won a partial victory in June in its fight against new safety regulations that some believe will effectively shut down the use of MRI across the European Union. But the Alliance for MRI, led by the European Society of Radiology (ESR) of Vienna, faces additional struggle in winning a permanent injunction against implementation of the rules.
