FDG-PET predicts early response to chemo in metastatic breast lesions

Properly identifying tumor response in the early treatment stages is vital, either to determine if additional courses of therapy are needed or if treatment should be discontinued. A group of gynecologists and radiologists have proposed using sequential F-18 FDG-PET for the early prediction of chemotherapy response, and hypothesized that changes in the pattern of FDG uptake would correlate with overall survival rates.

Breast cancer detected with screening mammo yields better prognosis

Finally, some good news for breast imagers -- breast cancer screening with mammography does offer a significant survival benefit in comparison to other cancer detection methods, according to an August 17 report in the Journal of the National Cancer Institute. In addition, this benefit exists in spite of two types of bias -- lead time and length -- that can skew detection data.

Coulda, woulda, shoulda: fMRI reveals neuroanatomy of regret

For most of us regret is all too familiar, an emotion that arises when we make a choice that turns out to be disadvantageous. But what is the specific brain change that takes place when we experience regret? French and British researchers used functional MRI (fMRI) to find an answer.

Observational EBT study finds estrogen-only HRT slows atherosclerosis

The onset of menopause has been tied to an increased risk of cardiovascular disease, but the exact role of hormone replacement therapy (HRT) is still a gray area. In a study using electron beam tomography (EBT), investigators from California evaluated the progression of coronary artery calcification (CAC) in relation to HRT in asymptomatic, postmenopausal women.

Hepatic and renal MRI streamline preop organ donor tests

Becoming a living organ donor is no doubt a harrowing and emotional process. So should a potential donor be subjected to a battery of imaging tests to determine his or her suitability? No, according to Korean clinicians who advocate a single modality exam with MRI for evaluating liver donors. Dutch researchers also recommend MR angiography (MRA) over digital substracation angiography (DSA) for assessing kidney donors.

Imaged-guided breast biopsy advances, but referring docs may not buy it

When it comes to the advantages of percutaneous breast biopsy over surgical excision, breast imaging experts are in the know -- image-guided biopsy can be performed quickly using local anesthesia, ensures better patient compliance, and is cost-effective. Unfortunately, this good news hasn't necessarily made its way to the offices of referring physicians. Two recent studies took a closer look at current techniques and trends in breast biopsy.

Breast biopsy rates hold steady despite new techniques

The advent of less invasive, more convenient image-guided biopsy techniques has not taken a toll on overall breast biopsy rates, which have remained fairly consistent over a 12-year period in one U.S. state, according to a study in the Archives of Internal Medicine.

Researchers make inroads with breast CT, gear up for clinical test

Thirty years after breast CT was introduced, abandoned, and then reintroduced, California researchers believe they have a viable breast CT unit that may detect tumors sooner than mammography. The group presented the results of their most recent research Sunday at the American Association of Physicists in Medicine (AAPM) meeting in Seattle.

Is a new study in the Journal of the National Cancer Institute (JNCI), which questions the benefit of breast cancer screening for reducing mortality, yet another example of how general medical journals are out to undermine the modality? Yes, according to a U.S. breast imaging specialist.
