Nuclear Medicine: The preoperative visualization of SLN with SPECT/CT is technically feasible and facilitates the detection of additional positive SLNs.

Preoperative three-dimensional (3D) visualization of sentinel lymph nodes (SLNs) used with single-photon emission computed tomography/computed tomography (SPECT/CT) imaging was associated with a higher rate of identification of positive SLNs and a higher rate of disease-free survival among patients with melanoma, according to new findings.

New opportunities radiology information system

A radiology information system (RIS) enables a web-based solution that streamlines workflow and enables providers to meet meaningful use (MU) criteria.

Siemens will offer new and improved diagnostic Ultrasound Equipment

Siemens Healthcare (Erlangen, Germany) announced that the company has entered into a definitive agreement to acquire substantially all of the assets of Penrith Corporation of Plymouth Meeting (PA, USA), a manufacturer of integrated ultrasound imaging systems. Through this acquisition, Siemens will offer new and improved diagnostic capabilities and expand its ultrasound portfolio. The transaction is expected to close in September 2012.

Radiography: New Data Provide Clues into Why Some Lung Tumors Are Undetected by X-Ray

New research has revealed why some lung tumors are undetected by X-ray and helped to identify the type of individuals who may be at risk of this sort of lung cancer.

Dentistry: In the treatment of dental caries helping coconut oil

Digested coconut oil is able to attack the bacteria that cause tooth decay. It is a natural antibiotic that could be incorporated into commercial dental care products, say scientists presenting their work at the Society for General Microbiology's Autumn Conference at the University of Warwick.

Radiography: Coronary computed tomographic angiography is a noninvasive anatomic test for diagnosis of coronary stenosis

Among patients with suspected or known coronary artery disease, use of a screening test that utilizes computational fluid dynamics to draw on specific data from computed tomographic (CT) angiography imaging demonstrated improved diagnostic accuracy vs. CT angiography alone for the diagnosis of ischemia.

Nuclear Medicine: Various methods of diagnosis of ovarian cancer

Because of the lack of relevant research, there is currently no substantial evidence that patients with ovarian cancer can benefit from positron emission tomography (PET) imaging alone or in combination with computed tomography (CT) imaging. As regards diagnostic accuracy, in certain cases, recurrences can be detected earlier and more accurately with PET or PET/CT than with conventional imaging techniques.
