Cardiac stress MR tops SPECT, showing cause of chest pain
By Eric Barnes
CHICAGO - Johns Hopkins researchers found that cardiac stress MRI not only outperforms SPECT for detecting acute myocardial infarction in patients presenting to the emergency room with chest pain, it reveals important information about the cause of the pain, even when symptoms are unrelated to coronary artery disease.

Radical robotic radiosurgery produces 'distinctive' PET/CT imaging pattern
By Wayne Forrest
CHICAGO - Researchers at Georgetown University Hospital in Washington, DC, have found that radical robotic radiosurgery results in a "distinctive PET/CT imaging pattern" following treatment, which likely is related to high radiation doses delivered 1 cm or more around the tumor.

Dual-head gamma camera increases breast lesion detection
By Kate Madden Yee
In what they believe is the first clinical study conducted using a dual-head configuration of a molecular breast imaging system, researchers at the Mayo Clinic in Rochester, MN, explored whether the use of this kind of system would increase the sensitivity of this modality.

Proton therapy reduces bone marrow toxicity compared with IMRT
By Edward Susman
Tighter control of how much radiation is focused on a tumor and how much affects adjacent structures appears to result in less bone marrow toxicity among patients treated with proton beam therapy, when compared with conventional intensity-modulated radiation therapy (IMRT).

Adenosine stress DECT equivalent to SPECT, MRI
By Eric Barnes
A new power combo consisting of adenosine stress and dual-energy CT (DECT) is delivering diagnostic accuracy equivalent to stress/rest cardiac MRI and nuclear perfusion (SPECT) for detecting perfusion defects, according to research presented at the American Heart Association meeting in New Orleans.

Dual-time-point FDG-PET/CT improves breast imaging accuracy
By Kate Madden Yee
Recent study results suggest that dual-time-point imaging with acquisition in the prone position improves PET/CT accuracy in patients with suspected breast cancer over single-time-point PET/CT. However, for lesions smaller than 10 mm, MRI shows higher sensitivity and should be preferred, according to the researchers.

PET, PiB support cognitive reserve hypothesis in Alzheimer's
By Wayne Forrest
A new study has found that people with more education appear to score higher on cognitive tests, despite having evidence of brain plaques associated with Alzheimer's disease. Researchers used the PET radiotracer carbon-11-labeled Pittsburgh Compound B (C-11 PiB) to image fibrillar beta-amyloid pathology in vivo.
