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.

JNCI: More sensitive breast screening needed

Interval breast cancers were larger, of more advanced stages, more poorly differentiated, more likely to have lymph node involvement and had a higher proliferation rate compared with matched screen-detected cancers, according to a study published in the May issue of the Journal of the National Cancer Institute, leading the authors to call for more sensitive screening modalities and different approaches for early detection of fast-growing tumors.

ARRS: PET/CT helps identify early-onset Alzheimers disease

CHICAGOPET/CT can help identify cognitive reserve in early-onset Alzheimers disease and may help effectively detect early-onset Alzheimers disease, according to a presentation on May 2 at the annual meeting of the American Roentgen Ray Society (ARRS).

FDA: More than 65,000 Defibtech AEDs recalled

Defibtech has voluntarily recalled 65,885 of its DDU-100 series semi-automatic external defibrillators (AEDs), sold under Lifeline and ReviveR AED brand names, after it realized some of these devices were shipped with 2.0044 software or earlier. The FDA has deemed this a Class I recall.

AJR: CT suffices for determining NSCLC tumor volume

Although PET and CT both offered concordance with histologic measurements of non-small-cell lung cancer (NSCLC), CT is often accurate for staging primary T1 and T2 NSCLC, according to a study published in this month's American Journal of Roentgenology.

Bristol-Myers recalls warfarin lots

Bristol-Myers Squibb has issued a voluntary recall of one lot of its 1,000-count bottles of Coumadin (warfarin) 5 mg tablets after the company found that one tablet had higher doses than expected.

Radiology: DOS tomography may inform individualized chemo

Diffuse optical spectroscopic (DOS) tomography imaging may help differentiate complete and partial responses to neoadjuvant chemotherapy among women with invasive breast cancer, according to a small pilot study published in this month's Radiology.

JNM: Longer scan + TOF PET is best for lesion detection, localization

A combination of longer scan time (of three minutes) and time-of-flight (TOF) PET imaging provides the best performance for imaging large patients or a low-uptake lesion in small or large patients, according to a study in the May issue of the Journal of Nuclear Medicine.
