AbstractMuscle ischemia and infarction are associated with a variety of pathologic conditions and commonly encountered in busy imaging practices. This article reviews the most common clinical scenarios in which they are seen including compartment syndrome, diabetic myonecrosis, and rhabdomyolysis, focusing on the imaging findings and differential diagnosis for each disease process. Magnetic resonance imaging is increasingly useful in differentiating myonecrosis from muscle ischemia and myositis, and it is highly accurate in diagnosing the most common type of compartment syndrome.

Abstract A rare case of a radiolucent osteoma of the skull is reported. The radiological and pathological findings of this lesion, including magnetic resonance imaging findings, are presented, and the efficacy of magnetic resonance imaging for the diagnosis of this skull tumor is evaluated. The differential diagnosis of radiolucent bone tumors is discussed.

Ischemic Encephalopathy

Background:Neonatal hypoxic-ischemic encephalopathy is brain injury caused by decreased perfusion and oxygen delivery that most commonly occurs in the context of delivery complications such as umbilical cord compression or placental abruption. Imaging is a key component for guiding treatment and prediction of prognosis, and the most sensitive clinical imaging modality for the brain injury patterns seen in hypoxic-ischemic encephalopathy is magnetic resonance imaging.Objective:The goal of this review is to compare magnetic resonance imaging findings demonstrated in the available animal models of hypoxic-ischemic encephalopathy to those found in preterm (≤ 36 weeks) and term (>36 weeks) human neonates with hypoxic-ischemic encephalopathy, with special attention to the strengths and weaknesses of each model.Methods:A structured literature search was performed independently by two authors and the results of the searches were compiled. Animal model, human brain age equivalency, mechanism of injury, and area of brain injury were recorded for comparison to imaging findings in preterm and term human neonates with hypoxic-ischemic encephalopathy.Conclusion:Numerous animal models have been developed to better elicit the expected findings that occur after HIE by allowing investigators to control many of the clinical variables that result in injury. Although modeling the same disease process, magnetic resonance imaging findings in the animal models vary with the species and methods used to induce hypoxia and ischemia. The further development of animal models of HIE should include a focus on comparing imaging findings, and not just pathologic findings, to human studies.

There are various pediatric magnetic resonance imaging (MRI) protocols followed in institutes and by individual radiologists, determined by the disease process and the indication for imaging, to narrow down the differential diagnosis. Most times, it is beneficial to modify protocols when the scans are being done, based on the findings seen on initially acquired sequences. This is particularly useful in pediatric patients considering most of them are scanned either under sedation or general anesthesia, and repeat scans will be cumbersome. In this particular review article, we are going to discuss appropriate MRI sequences in scanning pediatric brains and the need for rapid MRI sequences. This is of immense importance as MRI in pediatric patients poses challenges both to radiologists and technologists. Consequently, appropriate MRI protocols should be set to avoid repeat studies.

Characteristic Features

Abstract The aim of this pictorial essay is to review the spectrum of fat-containing liver lesions and their characterisation on magnetic resonance imaging with focus on the radiological features that aid in the differential diagnoses. Fat-containing liver lesions comprise a heterogeneous group of tumours with variable imaging findings. Magnetic resonance imaging clearly displays the micro- and macroscopic fat components of the lesions and other characteristic features that are helpful tools to make the differential diagnosis.

Invaluable Tool

The presence of intralesional fat provides an invaluable tool for narrowing the differential diagnosis for both benign and malignant neoplasms of the abdomen and pelvis. The ability to characterize intralesional fat is further expanded by the ability of magnetic resonance imaging to detect small quantities (intravoxel) of fat. The differential diagnosis of fat-containing lesions arising in the liver is broader than that of many other solid organs. However, this differential can be further refined depending on the type of fat (macroscopic vs intravoxel) and with the use of ancillary imaging findings. Radiologists must be aware of benign and malignant mimickers of common lesions.
