PET/CT predicts response to endorectal radiotherapy
January 30, 2013 -- PET/CT results can predict which patients will respond to high-dose-rate endorectal brachytherapy for stage II and III rectal cancer, according to a study presented at the American Society of Clinical Oncology Gastrointestinal Cancers Symposium. The results could pave the way for easier treatments and better outcomes.  Discuss
PET MPI with flurpiridaz F-18 tops SPECT MPI
January 30, 2013 -- PET myocardial perfusion imaging (MPI) with flurpiridaz F-18 is "safe and superior" to SPECT MPI with technetium-99m for image quality, interpretation, coronary artery disease diagnosis, and patient tolerance of the tracer, according to a study published in the January 29 issue of the Journal of the American College of Cardiology.  Discuss
Blacks treated less, die sooner from advanced colon cancer
January 29, 2013 -- When it comes to advanced metastatic colorectal cancer, blacks are less likely to be referred for treatment, less likely to receive it, and more likely to die sooner than whites, according to a study presented on Saturday at the American Society of Clinical Oncology Gastrointestinal Cancers Symposium.  Discuss
MDCT falls short in finding myocardial ischemia
January 29, 2013 -- In a comparison of patients with ischemia detected by SPECT or PET myocardial perfusion imaging, resting electrocardiogram-gated 64-slice MDCT proved "unsuitable" for clinical use, according to a study published in the February issue of the American Journal of Roentgenology.  Discuss
Arab Health: Disappearing women cause anguish after screening
January 29, 2013 -- DUBAI - Fresh data about the Egyptian breast cancer screening program released on the second day of Arab Health confirm that "unreachables" -- patients with suspicious cases who fail to show for follow-up -- remain a serious problem.  Discuss
Joint task force publishes brain amyloid PET criteria
January 28, 2013 -- A task force assembled by the Society of Nuclear Medicine and Molecular Imaging and the Alzheimer's Association has concluded that brain amyloid PET imaging could potentially help diagnose individuals with cognitive impairment if certain conditions are met.  Discuss
Lumpectomy with RT tops mastectomy for early-stage cancer
January 28, 2013 -- Women with early-stage breast cancer sometimes opt for mastectomy rather than less radical surgery out of concern about cancer recurrence. But recurrence risk was lower for women who chose lumpectomy followed by radiation therapy (RT) compared with those who received mastectomies, according to a study published online on Monday in Cancer.  Discuss
LED displays offer comfort without hindering performance
January 28, 2013 -- Without sacrificing diagnostic performance, monitors that employ light-emitting diode (LED) backlights are more comfortable to use for diagnostic interpretation than displays employing traditional backlighting based on cold cathode fluorescent lamp technology, Korean researchers have found.  Discuss
ASCO GI: CT unnecessary for staging early gastric cancer
January 25, 2013 -- SAN FRANCISCO - CT is unnecessary for staging gastric cancer owing to its poor sensitivity for diagnosing nodal involvement and the rarity of metastasis in patients with stage T1 disease, according to a Thursday presentation at the American Society of Clinical Oncology (ASCO) 2013 Gastrointestinal Cancers Symposium.  Discuss
Could a new breast MR protocol replace screening mammo?
January 25, 2013 -- Using a streamlined breast MR protocol for women with dense tissue takes less time and finds more early cancers than mammography -- potentially replacing it as a screening modality, according to research presented at the RSNA 2012 meeting.  Discuss
