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

Researchers have tested a new MRI technique, called quantitative susceptibility mapping (QSM), to track iron levels in the brains of multiple sclerosis patients. They found that brain iron levels can help identify those at a higher risk for developing physical disability, according to a new study published in the journal Radiology. Multiple...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

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

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
