Most comprehensive recommendations related to lung cancer

New evidenced-based guidelines from the American College of Chest Physicians (ACCP) recommend against the use of low-dose computed tomography (LDCT) for the general screening of lung cancer.

Nuclear medicine approach can be first choice for excluding pulmonary embolism in young women

Young women at risk of having a pulmonary embolism - a potential life-threatening blockage in a lung artery - should first undergo a ventilation/perfusion lung scan (V/Q scan) rather than a CT (computed tomography) angiogram, conclude authors in a paper published in the September Journal of Nuclear Medicine.

Laser technology detects cancer by scanning surface veins

A new technology for cancer detection that eliminates the need for drawing blood has been developed by Purdue University researchers.

Imaging is everything: What the clinician needs to know

In recent years, the concept of multimodality imaging has emerged coincident with advances in the newer technologies of Cardiac Magnetic Resonance (CMR) and Coronary Computed Tomography (CCT).

High-density diffuse optical tomography helps scan infant brains

Researchers hoping to better understand the development of the infant brain have long been stymied by a formidable obstacle: babies just don't want to sit still for brain scans.

PET MPI provides a more accurate "picture" of coronary obstruction

Physicians need to know how badly heart vessels are blocked before they can decide how to treat patients at risk of having a heart attack.

First 3D images of a living cell

A new imaging technique developed at MIT has allowed scientists to create the first 3D images of a living cell, using a method similar to the X-ray CT scans doctors use to see inside the body.

Imaging technique accurate in aneurysm detection and therapy planning

Multidetector computed tomography (MDCT) angiography is highly accurate in depicting intracranial aneurysms, according to a study published in the August issue of Radiology.

Cancer risk from radiation during cardiac CT scans studied

An analysis based on computerized simulation models suggests that the lifetime risk of cancer associated with radiation exposure from a computed tomography (CT scan) coronary angiography varies widely, with the risk greater for women and younger patients, according to a study in the July 18 issue of JAMA .

Suped-up computed tomography scanners

By borrowing techniques used in telecommunications technology, computed tomography (CT) scanners may eventually see data collection speeds increase by hundreds of times, leading to better images, faster imaging procedures, and potentially lower x-ray exposures.

Life near the highway bad for the heart

According to German researchers living near a busy highway may be bad for your heart as it raises the risk of hardening of the arteries.

Study shows inaccuracies in cardiac PET-CT imaging

Current PET-CT scanners with standard commercial software designed to provide images of the heart are falsely indicating coronary artery disease in as many as 40 percent of patients, according to a study published today on the cover page of the Journal of Nuclear Medicine.

More fat may have some advantages for type 1 diabetes and heart disease

Researchers at the University of Pittsburgh Schools of the Health Sciences studying links between an early sign of heart disease called coronary artery calcification and body fat have found that, paradoxically, more fat may have some advantages, at least for people particularly women who have type 1 diabetes.
