CT venography offers DVT alternative to ultrasound in ICU

By Erik L. Ridley

Indirect CT venography (CTV) and duplex venous sonography turn in similar performance for evaluating acute deep vein thrombosis (DVT) in ICU patients with suspected pulmonary embolism, according to an article in the August American Journal of Roentgenology.

Management strategies evolve as CT finds more lung nodules

By Eric Barnes

CT's rapidly advancing capabilities, aimed at catching more cancers while they're potentially curable, have been the driving force behind the growth of lung cancer screening trials over the past decade. But what to do with the proliferation of lung nodules? Two thoracic imaging experts discuss the impact of CT's growing screening database, and offer advice on which nodules to biopsy, follow, or even ignore.

Nebraska launches free CT lung cancer screening

By AuntMinnie.com staff writers

A statewide consortium in Nebraska said it will soon begin recruiting smokers and former smokers for a statewide lung screening study, with CT scans to be performed annually for five years.

Even in pregnancy, CT rules for ruling out PE

By Eric Barnes

There's no cause for misgivings when CT pulmonary angiography is needed to rule out pulmonary embolism in a pregnant woman. CTPA not only provides the most definitive diagnosis available in such patients, it does so with less radiation than scintigraphy.

Part I: Computer-aided detection marking new targets

By Wayne Forrest

When healthcare practitioners think of computer-aided detection (CAD) technology today, they usually consider using it with mammography for early breast cancer detection. As technology and research progress, however, there is a developing consensus among radiologists that CAD can aid in uncovering abnormalities in applications such as breast MRI, lung cancer screening, and virtual colonoscopy exams.

Gadolinium effective in CTA of pulmonary circulation

By N. Shivapriya

Gadolinium-based contrast agents, usually reserved for MR imaging, can provide diagnostic CT angiograms of pulmonary circulation with 16-detector-row CT, and can be used as an alternative to iodinated contrast in patients with contraindications for iodinated agents, according to researchers from France.

Lung PET rules when CT is equivocal, discordant

By Eric Barnes

Although PET's high cost ensures that CT and radiography will remain the first-line lung cancer detection modalities for at least the near future, PET can be very useful adjunctively in patients whose diagnosis remains uncertain in the light of available radiographic and clinical evidence.

PET/CT provides cost-savings for NSCLC radiotherapy

By Jonathan S. Batchelor

PET/CT technology has been demonstrating superior diagnostic and staging capabilities for various malignancies in scientific studies. But the technology comes at a steep price point, and models for its economic efficiencies are still being created. However, researchers from Canada have found PET/CT to be cost-effective in radiation therapy planning for non-small cell lung cancer (NSCLC).

3D diminution index spots lung nodules attached to blood vessels

By Eric Barnes

BERLIN - A principal limitation of lung cancer imaging is the difficulty of distinguishing lung nodules attached to blood vessels from normal blood vessels, especially in CT data. But researchers from Japan have developed a 3D feature called the diminution index, which scans the CT pulmonary blood vessel data for signs of rapidly expanding shapes that can indicate a nodule rather than a blood vessel.

3D rendering captures SNM's Image of the Year

By Jonathan S. Batchelor

TORONTO - A 3D volumetric virtual bronchoscopy rendering was named the 2005 Image of the Year at the Society of Nuclear Medicine (SNM) meeting on Monday. The Stanford University study was designed to validate a PET/CT acquisition and image processing protocol to produce 3D rendered fusion images.
