Paediatric head trauma is an important cause of morbidity and mortality in children and may be seen in the setting of accidental or abusive injuries. Many of the patterns of head injury are similar to adults, but it is worth noting that the imaging manifestations of head injury in children are more complex due to the developing brain and calvarium,...Read more

Radiomics is a hot topic in radiology. A steadily increasing number of researchers across the globe is engaging in radiomics and applying it to a large number of imaging data. “Radiomics” means the extraction of a large number of quantitative imaging features from routinely acquired imaging data (e.g, x-ray, ultrasound, CT, MRI, PET) in order to...Read more

Safety screening is an essential prerequisite to magnetic resonance imaging (MRI). Radiologist approval is often required to determine whether MRI can proceed safely in patients with medical and cosmetic devices or embedded foreign bodies. Although many sources of safety information are available online, MRI may be delayed or cancelled, especially...Read more

Cerebral venous thrombosis (CVT) is a rare disease, and with poor prognosis. Computed tomography (CT) and magnetic resonance imaging (MRI) are the most commonly used image modalities for patients with non-specific neurologic symptoms. A new meta-analysis assessed the accuracy of CT and MRI in the differential diagnosis of CVT and cerebral venous sinus...Read more

The use of diagnostic imaging has increased significantly over the past decade, and expensive technologies such as CT and MRI have been extensively introduced into several diagnostic procedures. While the clinical information acquired from their use may be beneficial to patients, these diagnostic tests also lead to increased healthcare costs. New research...Read more

Abdominal pregnancy is a rare type of ectopic pregnancy that is potentially life-threatening for both the mother and foetus. This dangerous medical condition can be easily missed in routine obstetric practice, even in routine antenatal ultrasonography. A new study in China highlights the importance of magnetic resonance imaging (MRI) in abdominal pregnancies,...Read more

Magnetic resonance imaging (MRI) of the spine is the preferred diagnostic tool for pathologic conditions affecting the spine. However, in patients receiving epidural corticosteroid injection (ESI) for treatment of spinal diseases, interpretation of MR images acquired after the injection might be confusing or impossible. According to a Korean study,...Read more

According to new research, echogenic nonshadowing renal lesions larger than 4 mm seen at ultrasound should not be assumed to represent an angiomyolipoma (AML) without follow-up because a percentage of renal cell carcinomas will be missed. "Although certain ultrasound features can be useful in differentiating an AML from a renal cell carcinoma and CT...Read more
