According to new research published in Academic Radiology, a 70 degree lead tip angle was found to ensure diagnostic image quality of all modalities in CT pacemaker imaging, leading authors to dub it the “magic angle.”

In recent research, Johns Hopkins University researchers demonstrated success in utilizing cardiac imaging to predict the effectiveness of using catheter ablation to treat atrial fibrillation (AFib).

For patients in the intensive care unit (ICU), a successful cardiothoracic MRI is challenging but beneficial for those with intact renal function, according to a new retrospective study published in Academic Radiology

A new method to capture images of the biomechanical properties of the heart may soon be a technique used to heal heart attack victims.

While the benefits of resistance training on musculoskeletal health are on daily display in any weightlifting room, the question of how much good all those sets and reps do for the heart has been open. Now comes an imaging-based answer from Germany, where researchers using MRI found measurable cardiac changes in a randomized group of novice male “gym rats” after they’d worked out regularly for around half a year.

Routine CTCA for chest pain could cut heart attack rates

CT coronary angiography (CTCA) can clarify the diagnosis of angina due to coronary heart disease, leading to a reduced need for further stress testing and enabling more targeted interventions. Ultimately, changes in treatments stemming from the addition of CTCA to standard clinical care could reduce fatal and non-fatal heart attack rates, according to the SCOT-HEART study.

From the heart: Imaging at ACC.15

Tomorrow in San Diego, thousands will gather to kick off the start of the American College of Cardiology’s Annual Scientific Session & Expo, which runs from March 14 – 16. Cutting-edge imaging in the cardiology space will be on display throughout the conference, from the late-breaking trials to the educational sessions.

Imaging at ACC.15: Session Spotlight

The focus of the cardiology world will be on San Diego for the American College of Cardiology’s Annual Scientific Session & Expo on March 14–16. As usual, imaging will be featured prominently, so read on to learn about the can’t-miss imaging sessions at ACC.15.

Cardiac CT as effective as TEE in predicting recurrent stroke

Transesophageal echocardiography (TEE) is the imaging modality of choice for doctors treating patients with ischemic stroke, but cardiac CT is just as effective at predicting recurrent strokes, according to a study published in the March issue of Radiology.

3D-printed bioplastics could be the future of interventional radiology

Devices and treatments specifically designed to match individual patient anatomy using 3D printing technologies and resorbable bioplastics are effective at providing targeted treatments against infection and cancer, according to a study presented at the Society of Interventional Radiology’s Annual Scientific Meeting.

MRI-safe pacemaker 100 percent free of adverse events in clinical trial

A clinical trial involving Biotronik’s ProMRI pacemaker has shown the model is safe for use during head and lower-back MRI scans, according to results published in the journal Heart Rhythm.

‘Emergency room on wheels,’ complete with CT scanner, speeds delivery of care to stroke patients

Providing emergency care to victims of stroke is all about timing—the swifter the response of emergency medical services, the better the chances become for favorable patient outcomes. New Mobile Stroke Treatment Units (MSTU) outfitted with CT scanners and staffed with nurses, paramedics and CT technologists are helping to shave critical minutes off of stroke response times.

Doppler US aids decisions in stroke prevention measures

Doppler ultrasonography (US) is an effective and relatively low-cost tool in identifying patients with asymptomatic carotid stenosis who would most benefit from more invasive treatment, according to a study published in the February edition of Radiology.

New multiphase CT aids stroke imaging

When imaging acute ischemic stroke (AIS) patients, a new CT angiography imaging method proved to be a reliable tool for imaging selection, according to a Canadian study published online Jan. 29 in Radiology.

MRA results are accurate, fast in stroke patients

Time-resolved MR angiography (MRA) has proven itself a valuable tool in the quick assessment of vascular disease in stroke patients, according to a study published online Jan. 15 in Academic Radiology.
