The scapula plays a central role in shoulder motion and stability. A wide variety of anatomic variants as well as traumatic, neoplastic, and infectious pathologies can involve the scapula. Detection of scapular lesions using radiography can be challenging because of the obscuration by the overlying structures or incomplete imaging during shoulder magnetic resonance imaging or computed tomography examinations. Familiarity with imaging characteristics of these abnormalities will allow radiologists to better diagnose and characterize scapular disorders...

Portal vein thrombosis (PVT) is a frequent complication of liver cirrhosis, but it can also occur as a primary vascular disorder amid absent liver disease. Extrahepatic portal vein obstruction (EHPVO) refers to the obstruction of the extrahepatic portal vein with or without involvement of the intrahepatic portal vein branches, splenic and/or superior mesenteric vein. It is a distinct disorder that excludes PVT occurring in concurrence with liver cirrhosis or hepatocellular carcinoma. The term "EHPVO" implies chronicity and is principally reserved for a long-standing condition characterized by cavernous transformation of the portal vein...

Aortic valve stenosis is the most common valvular heart disease in the Western world. When symptomatic, aortic valve stenosis is a debilitating disease with a dismal short-term prognosis, invariably leading to heart failure and death. Elective surgical valve replacement has traditionally been considered the standard of care for symptomatic aortic valve stenosis. However, several studies have identified various subgroups of patients with a significantly elevated risk for surgery-related complications and death...

Appendicitis, intussusception, and hypertrophic pyloric stenosis (HPS) are three of the most common reasons for emergent abdominal imaging in pediatric patients. Although the use of computed tomography has risen dramatically over the past 2 decades, children are particularly at risk for the adverse effects of ionizing radiation, and even low-dose radiation is associated with a small but significant increase in lifetime risk of fatal cancer. In most emergency departments, the use of magnetic resonance (MR) imaging as a primary modality for the evaluation of a child with abdominal pain remains impractical due to its high cost, its limited availability, and the frequent need for sedation...

Postpartum hemorrhage is among the most common causes of maternal morbidity and mortality. Postpartum hemorrhage is defined as a blood loss of greater than 500 mL or any amount that, if not replaced, could cause shock or death in the mother. The most common cause of postpartum hemorrhage is uterine atony. This occurs when the normal myometrium fails to contract after delivery of the placenta. The initial treatment involves the administration of intravenous oxytocin and uterine massage. If the initial maneuvers fail to stop the postpartum hemorrhage, other techniques, such as uterine packing, suture techniques, uterine or hypogastric artery ligation, can be considered...

We present a pictorial review of neonatal ischemic brain injury and look at its pathophysiology, imaging features and differential diagnoses from a radiologist's perspective. The concept of perinatal stroke is defined and its distinction from hypoxic-ischemic injury is emphasized. A brief review of recent imaging advances is included and a diagnostic approach to neonatal ischemic brain injury is suggested.

Charcot neuroarthropathy (CN) occurs commonly in diabetic patients in the joints of the foot and ankle. Radiologists may be the first to suggest the diagnosis of CN and can facilitate prompt intervention and treatment if they are aware of the radiographic manifestations of CN and the signs of progression of disease. Radiologists should also become aware of the evolving treatment of the disease as focus is shifting toward early surgical intervention and limb salvage rather than amputation. Knowledge of preoperative assessment, the types of surgeries performed, and some of the encountered postoperative complications enable the radiologist to facilitate timely intervention by our surgical colleagues and be a valuable member of the management team...

The use of magnetic resonance (MR) imaging is growing exponentially, in part because of the excellent anatomic and pathologic detail provided by the modality and because of recent technologic advances that have led to faster acquisition times. Radiology residents now are introduced in their 1st year of training to the MR pulse sequences routinely used in clinical imaging, including various spin-echo, gradient-echo, inversion-recovery, echo-planar imaging, and MR angiographic sequences. However, to make optimal use of these techniques, radiologists also need a basic knowledge of the physics of MR imaging, including T1 recovery, T2 and T2* decay, repetition time, echo time, and chemical shift effects...
