Medical Imaging

Physicians utilize medical imaging to see inside the body to diagnose and treat patients. This includes computed tomography (CT), magnetic resonance imaging (MRI), X-ray, ultrasound, fluoroscopy, angiography, and the nuclear imaging modalities of PET and SPECT.

'Breakthrough' MRI contrast design could make GBCAs safer, more effective
Researchers are hopeful their new approach to developing MRI contrast will "pave the way for safer, smarter imaging in clinical diagnostics."
MRIs show how peanut consumption improves the brain's vascular function
Consistently incorporating unsalted peanuts into a person’s diet enhances cerebral blood flow to multiple brain regions.
CCTA will play an essential role in the cath labs of the future
Noninvasive coronary CT angiography is growing more and more important as time goes on, helping cardiologists make critical treatment decisions. Carlos Collet, MD, PhD, discussed the technique's potential to be a real game-changer for patient care in a new interview.
Society of Interventional Radiology urges UHC to update policy on radioembolization treatment
SIR contends that payments toward transarterial radioembolization (TARE)/selective internal radiation therapy (SIRT) should extend beyond the current coverage limitations in patients with liver cancer and metastases.
RadNet acquires remote MRI scanning solutions provider Alpha RT
The company offers a suite of services including AI-powered safety monitoring in case something goes wrong in the MRI suite, staffing, training and certification.

Cardiac CT imaging has been moved to the forefront of medical imaging to evaluate chest pain under the new 2021 chest pain guidelines from the AHA and ACC. #Yescct #CCTA #CTA #CT

VIDEO: The new role of cardiac CT under the 2021 chest pain evaluation guidelines

Eric Williamson, MD, president of the Society of Cardiovascular Computed Tomography (SCCT) and professor of radiology at Mayo Clinic, explains the rapid rise of interest in cardiac CT imaging following its inclusion as a top recommendation in the ACC 2021 Chest Pain Evaluation Guidelines.

Mammography AI intercepts density overestimations

Researchers have demonstrated a deep learning model that can correct course for breast radiologists who otherwise may have erroneously deemed tissue dense in screening exams.

Some respiratory face masks are unsafe for MRIs, study finds

Five out of eight filtering face piece (FFP-3) masks studied contained ferromagnetic components.

Eric Williamson, MD, MSCCT, the president of the Society of Cardiovascular Computed Tomography (SCCT) and professor of radiology at Mayo Clinic, explains how the iodine contrast shortage is causing issues for cardiac CT imaging. He discusses ways imagers can stretch they iodine contrast supplies and some technologies that might help conserve contrast. #contrastshortage

VIDEO: Contrast media shortage impacting cardiac CT imaging

Eric Williamson, MD, president of the Society of Cardiovascular Computed Tomography (SCCT) and professor of radiology at Mayo Clinic, explains how the iodine contrast shortage is causing issues for cardiac CT imaging and ways this can be mitigated.

Researcher considers greater role of AB-MRI for patients with personal history of breast cancer

Post-treatment changes may mask some of the subtle, early signs of recurring breast cancer on traditional mammography, an Academic Radiology editorial explains.

Claims review may guide evidence-based approach to contrast-shortage mitigation

Iodinated contrast is most widely used in patients undergoing CT studies for, in descending order, abdominopelvic, chest, head/neck and brain indications.

A comparison between a traditional iodine contrast angiogram (left), and a gadolinium contrast angiogram (right). MRI gadolinium contrast is starting to be used in some interventional radiology procedures and is being considered in interventional cardiology due to the iodine contrast shortage.

Gadolinium can be used as substitute for iodine contrast in some interventional imaging procedures

Gadolinium might be an alternative, stop-gap solution for interventional procedures during the current iodine contrast shortage.

Deep learning model accurately detects COVID-19 on chest X-ray images

Is it pneumonia or COVID-19? With the help of artificial intelligence, a chest X-ray can reveal the answer.
