IMAGING Management

2018 06 Jun

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...

MRI: rapid determination of implant safety status

2018 02 May

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

Both CT, MRI can accurately detect cerebral venous thrombosis

2018 02 May

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

Inappropriate CT and MRI use in hospitalised patients

2018 22 Feb

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

MRI detects abdominal pregnancy better than ultrasonography

2018 23 Jan

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

Measuring exposure of workers in MRI environment

2018 17 Jan

Magnetic resonance imaging (MRI) facilities are important sources of multiple exposure to electromagnetic fields for both patients and healthcare staff. In an exploratory study, researchers conducted an exposure assessment and biomonitoring of MRI workers at the Radio-diagnostics Unit of the National Cancer Institute of Naples “Pascale Foundation”...

Effect of epidural steroid injection on MRI findings

2017 22 Nov

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

The utility of MRI for diagnosing angiomyolipoma

2017 14 Nov

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

MRI and clinical outcome in carotid artery stenosis after revascularisation

2017 07 Nov

Researchers in Poland performed a prospective study to assess functional and cognitive outcome, with regard to cerebral flow on transcranial Doppler (TCD) and brain magnetic resonance imaging (MRI) in patients with symptomatic carotid artery stenosis (CAS) referred for carotid artery revascularisation (CAR). Their findings indicate that early revascularisation... Read more

New Metamaterial-Enhanced MRI Technique

2017 30 May

Scientists from Leiden University Medical Center in the Netherlands and ITMO University in Russia have designed and tested a new metasurface-based technology that can enhance the local sensitivity of MRI scanners on humans. This metasurface consists of thin resonant strips that are arranged periodically. When placed under the patient's head, this metasurface... Read more
