NYU Langone offers chance to participate in lung cancer early detection study

NYU Langone Medical Center is a pioneer in lung cancer screening and offers comprehensive screening for individuals at risk for lung cancer. The NYU Langone Lung Cancer Screening Center is distinguished by its multidisciplinary approach and wealth of experience and is under the direction of the Divisions of Pulmonary Medicine, Thoracic Radiology and Thoracic Surgery.

Recurrences of ovarian cancer can be detected earlier and more accurately with PET/CT

Due to the lack of studies, there is currently no proof that patients with ovarian cancer can benefit from positron emission tomography (PET) alone or in combination with computed tomography (CT). 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.

Advanced Radiology to offer Amyvid for detection of AD

Advanced Radiology, a division of RadNet, Inc., a national market leader providing high-quality, cost-effective diagnostic imaging services through a network of 237 fully-owned and operated outpatient imaging centers, announced it will be one of a small number of imaging centers in the U.S. to offer Amyvid, a radioactive tracer used in positron emission tomography – computed tomography (PET/CT) imaging that helps to detect the quantity of beta-amyloid plaque in patient's brains.

SPECT/CT with 99mTc-HMPAO-WBC can improve diagnosis of infectious endocarditis

When combined with standard diagnostic tests, functional imaging procedures have been shown to reduce the rate of misdiagnosed cases of infectious endocarditis. According to new research published in the August issue of The Journal of Nuclear Medicine, single photon emission computed tomography (SPECT)/computed tomography (CT) with 99mTc-hexamethylpropleneamine oxime-labeled white blood cells (99mTc-HMPAO-WBC) can improve the diagnosis of infectious endocarditis in hard-to-diagnose cases.
