Multipurpose CT lung cancer screening more cost-effective
CT lung cancer screening is likely to be more cost-effective if it is used to identify other tobacco-related conditions in high-risk people, according to a study published in the Journal of Thoracic Oncology.

Subsolid lung nodule assessment with CT evolves
As their experience with subsolid nodules at CT grows, radiologists are learning more about their characteristics and potential risk of malignancy. Overall, the past several years have seen nodule size and growth rise in importance relative to CT density, a less reliable predictor of malignancy.

Holography beckons as alternative to 3D printing
For all its proven value, 3D printing is just one of many ways to look at 3D data -- and it's a rather rigid one at that. For clinicians, understanding a patient's medical condition may require more than a printed skull or aneurysm. In these cases, a holographic dataset can be helpful.

ISCT: The long road to full automation in abdominal CT
SAN FRANCISCO - The past few years have seen rapid progress toward the goal of automated abdominal CT analysis using multiple computer-aided-detection systems, all theoretically applied to a single abdominal CT angiography dataset, according to a Tuesday presentation at the International Society for Computed Tomography (ISCT) symposium.

ISCT: Value of CT depends on who's looking
SAN FRANCISCO - Gauging the value of a CT scan is the single most critical reason for deciding whether to perform an exam. But when you get down to it, value depends on what you're looking for and who's looking at it, according to talks on Sunday at the International Society for Computed Tomography (ISCT) annual meeting.

CT detects frailty and predicts survival in elderly
CT scans are going beyond identifying broken bones to detecting skeletal frailty in the elderly, and even predicting their ability to survive a fall, according to a study in the June edition of the American Journal of Roentgenology.

3D-printed mouse ovaries yield healthy offspring
The promise of 3D-printed functional organs took a big step forward with the recent implantation of 3D-printed ovaries in mice. The bioprosthetic ovaries enabled the animals to ovulate and give birth to healthy pups, according to a study published online May 16 in Nature Communications. The mothers were even able to nurse their young.

SPECT/CT predicts foot amputations in diabetics

Examples in two patients. (Top) Abnormal leukocyte accumulation was observed in the right 1st to 5th toes, with the radioactive lesions extending to the bone, indicating osteomyelitis (left panel, MIP image; right panel, axial SPECT/CT). Two spherical VOIs were drawn on diabetic foot infections (DFIs) and the highest SUVmax was 4.2 (higher than the cutoff of 1.1) Despite intensive treatment, the infection progressed, leading to the patient undergoing right below knee amputation 43 days after SPECT/CT. (Bottom) Mild focal abnormal leukocyte accumulation was detected in the right 3rd and 4th toes. The lesions were in contact with the bone, which raised a suspicion of osteomyelitis (left panel, MIP image; right panel, axial SPECT/CT). A circular VOI was drawn on DFIs and the SUVmax was 1.0 (lower than the cutoff of 1.1). After 10 weeks of antibiotic treatment, the infection was successfully resolved, and the foot was preserved.
