Comparative Evaluation of Iodine-125 Radioactive Seed Localization and Wire Localization for Resection of Breast Lesions
Radioactive seed localization (RSL) uses a titanium seed labeled with iodine-125 energy for surgery of nonpalpable breast lesions. RSL facilitates radiology –surgery scheduling and allows for improved oncoplasty compared with wire localization (WL). The purpose of this work was to compare the 2 techniques.

Antithrombotic Use Predicts Recanalization of Embolized Pulmonary  Arteriovenous Malformations in Hereditary Hemorrhagic Telangiectasia
Pulmonary arteriovenous malformations (PAVMs) are most commonly seen in association with hereditary hemorrhagic telangiectasia (HHT), also known as Osler-Weber-Rendu syndrome [1]. Standard treatment is coil embolization, as PAVMs can cause stroke and cerebral abscesses [2] due to a paradoxical shunt, and pulmonary complications such as spontaneous hemothorax and hemoptysis. PAVM recanalization is an important finding that may lead to paradoxical embolism. Previous studies [3,4] have demonstrated increased feeding artery diameter, low number of coils, use of oversized coils, and proximal coil placement within the feeding ar...

FRAX vs CAROC for the Canadian Imaging Physician: An Existential Dilemma
Imaging physicians (radiologists and nuclear medicine specialists) at some Canadian bone mineral density (BMD) centers find themselves under pressure to report fracture risk using the Fracture Risk Assessment Tool (FRAX) tool rather than the Canadian Association of Radiologists and Osteoporosis Canada (CAROC) platform. The question arises: is this a realistic expectation? (Source: Canadian Association of Radiologists Journal)

Magnetic Resonance Signal Abnormalities Within the Pericruciate Fat Pad: A Possible Secondary Sign for Acute Anterior Cruciate Ligament Tears
The study sought to investigate the presence of magnetic resonance (MR) signal alterations within the pericruciate fat pad in patients with an acute anterior cruciate ligament (ACL) tear as well as evaluate its diagnostic value in comparison with the main secondary signs of ACL tears.

Brain Diffusion Changes in Polycystic Ovary Syndrome
Polycystic ovary syndrome (PCOS) is the most frequent endocrine disorder in women of reproductive age, affecting 4%-10% of the population. It is a complex disorder classically characterized by chronic oligo- or anovulation, polycystic ovaries, and hyperandrogenism. It is also associated with a number of comorbid conditions, including type 2 diabetes, cardiovascular disease, dyslipidemia, obesity, infertility, and breast and endometrial cancer [1,2]. In addition, psychiatric disorders are observed more often in PCOS patients than in the general population, particularly depressive, anxiety, and eating disorders [3 –6]. (So...

Imaging of Ankle Impingement Syndromes
Ankle impingement syndromes are a commonly encountered clinical entity seen in athletes, secondary to repetitive forceful microtrauma. Symptoms are related to impingement of osseous or soft tissue abnormalities in the ankle joint, in particular the tibiotalar joint, which may result in painful limitation of ankle movements. Imaging modalities, such as radiographs and magnetic resonance imaging, are very useful in diagnosing osseous and soft tissue abnormalities seen in different types of ankle impingement syndromes.

Risk Stratification in Multinodular Goiter: A Retrospective Review of Sonographic Features, Histopathological Results, and Cancer Risk
In the management of thyroid nodules, although the potential for malignancy exists, there is also the potential for overtreatment of subclinical disease. Although the TI-RADS (Thyroid Imaging-Reporting and Data System) system outlines a risk stratification score based on suspicious ultrasound findings, it has not been universally accepted. Many TI-RADS 2 or 3 patients proceed to fine needle aspiration biopsy (FNAB), potentially unnecessarily. The aim of the study was to identify whether lesions within a multinodular goiter (MNG) without suspicious features can be followed with ultrasound rather than biopsied as is recommen...

The Positive Outcome of MRI-Guided Vacuum Assisted Core Needle Breast Biopsies Is Not Influenced by a Prior Negative Targeted Second-Look Ultrasound
The study sought to investigate the outcome of breast magnetic resonance –guided biopsies as a function of the indication for magnetic resonance imaging (MRI), the MRI features of the lesions, and the performance or not of a targeted second-look ultrasound (SLUS) prior breast MRI-guided biopsy.
