INTRODUCTION: MRI evaluation in facioscapulohumeral muscular dystrophy (FSHD) demonstrates fatty replacement and inflammation/edema in muscle. Our previous work demonstrated Short T1 Inversion Recovery (STIR)-hyperintense (STIR+) signal in muscle 2 years prior to fatty replacement. We evaluated leg muscle STIR changes and fatty replacement within 14 months. METHODS: FSHD subjects received 2 MRI scans of thigh and calf over a 6.9-13.8 month interval. Quality of life measures were collected...

REVIEW
A G Schreyer
BACKGROUND: Mesenterial and peritoneal inflammation represents a major clinical challenge regarding differential diagnosis. In this review article, a systematic overview of the most common causes such as autoimmune reaction, infarction with consecutive necrosis and infection caused by protozoa or bacteria is provided. RESULTS: The common clinical features of all inflammatory peritoneal and mesenterial diseases are the nonspecific abdominal symptoms. Even in radiological imaging an overlap of imaging features such as lymphadenopathy and nodular mesenteric structures is typical...

BACKGROUND: The management of rectal cancer has evolved over the years, including the recent rise of Transanal Total Mesorectal Excision (TaTME). TaTME addresses the limitations created by the bony confines of the pelvis, bulky tumours, and fatty mesorectum, particularly for low rectal cancers. However, guidance is required to ensure safe implementation and to avoid the pitfalls and potential major morbidity encountered by the early adopters of TaTME. We report a broad international consensus statement, which provides a basis for optimal clinical practice...

REVIEW
M Juchems
CLINICAL/METHODICAL ISSUE: Gastroenteropancreatic neuroendocrine neoplasia (GEP-NEN) are a heterogeneous group of complex tumors, which is often difficult to classify due to heterogeneity and varying locations. STANDARD RADIOLOGICAL METHODS: Ultrasound, computed tomography (CT), magnetic resonance imaging (MRI) and positron-emission tomography computed tomography (PET/CT) are available for the localization of NEN as well as for the staging. METHODOLOGICAL INNOVATIONS: In particular, nuclear medical examination methods with somatostatin analogues are of great importance since radioactively labeled receptor ligands make tumors visible with high sensitivity...

PURPOSE OF REVIEW: Options for prostate cancer management are rapidly expanding. The recent advent of MRI technology has led to guided prostate biopsies by radiologists working in-bore or by urologists using MR/US fusion technology. The resulting tumor visualization now provides the option of focal therapy. Currently available are highly directed energies - focused ultrasound (HIFU), cryotherapy, and laser - all offering the hope of curing prostate cancer with few side effects. RECENT FINDINGS: MRI now enables visualization of many prostate cancers...

There is little doubt that the worldwide Cesarean delivery epidemic has led to an increased incidence of abnormally adherent and invasive placentation. The significant impact that this disorder has on maternal morbidity and mortality has led to a flurry of publications in the literature concerning all aspects of the condition. These papers have arisen from many sources, notably pathologists, epidemiologists, obstetricians and radiologists.

Liver-directed therapy is a critical component of treatment strategies for hepatocellular carcinoma. These therapies included percutaneous image-guided ablation, transarterial chemoembolization, and transarterial radioembolization, and are administered by interventional radiologists. Depending on the stage of disease, a particular treatment modality, or a combination thereof, is expected to be most efficacious in achieving the goals of treatment for a particular patient. This article seeks to review the various liver-directed treatment modalities for treatment of hepatocellular carcinoma, with attention to their efficacy and patient selection criteria...

There are no accepted methods to grade bone marrow oedema (BMO) and fracture on magnetic resonance imaging (MRI) scans in Charcot osteoarthropathy. The aim was to devise semiquantitative BMO and fracture scores on foot and ankle MRI scans in diabetic patients with active osteoarthropathy and to assess the agreement in using these scores. Three radiologists assessed 45 scans (Siemens Avanto 1.5T, dedicated foot and ankle coil) and scored independently twenty-two bones (proximal phalanges, medial and lateral sesamoids, metatarsals, tarsals, distal tibial plafond, and medial and lateral malleoli) for BMO (0-no oedema, 1-oedema < 50% of bone volume, and 2-oedema > 50% of bone volume) and fracture (0-no fracture, 1-fracture, and 2-collapse/fragmentation)...

We report a case of renal artery pseudoaneurysm at the anastomosis site complicated with arterioureteral fistula (AUF) in a 57-year-old kidney transplant recipient who presented with intermittent massive hematuria at one month post-transplant. We successfully treated the pseudoaneurysm and AUF with endovascular covered stent implantation. The diagnosis of AUF is rare and it is a condition that occurs in patients with previous pelvic or vascular surgery, chronic ureteral catheterization and radiotherapy. This diagnosis requires the expertise of the urologist, vascular surgeon and interventional radiologist...
