Can a single, specialized MRI scan replace bone and CT scans for men with high-risk prostate cancer?

A recent paper by a team of Belgian researchers has suggested that diffusion-weighted. whole-body magnetic resonance imaging (DWWBMRI) may be able to replace historic forms of imaging — bone scans and contrast-enhanced CT scans and/or standard MRIs of the pelvis in the work-up of men at high risk for metastatic prostate cancer. … READ MORE …

Bone scan “flare” associated with treatment with abiraterone acetate

A new paper in Clinical Cancer Research indicates that at least some men will have a short-term bone scan “flare” as a consequence of initiation of treatment with abiraterone acetate. The clinical significance of this flare is still to be fully evaluated. … READ MORE …

Who really needs a bone scan at time of diagnosis?

Every year tens of thousands of men newly diagnosed with prostate cancer are given a bone scan (and other types of scan) as part of their “normal” diagnostic work-up. The only value of the bone scan is that it is able to identify men who already have (or at least may have evidence suggesting) actual metastatic prostate cancer to their bones at the time of diagnosis. … READ MORE …

Over- and under-imaging of newly diagnosed prostate cancer patients

This is hardly a radical new finding but yet another study has recently shown that we are over-using expensive scanning tests in the work-up of patients diagnosed with low- and intermediate-risk prostate cancer — and under-using these tests in men initially diagnosed with high-risk disease. … READ MORE …

Radioisotope shortage may impact availability of bone scans

For some time we have been monitoring a problem with the supply of the radioisotopes used in bone scans for patients suspected to have metastatic prostate cancer to their bones. … READ MORE …

  • The role of bone scans in diagnosis of men with PSA levels below and above 20 ng/ml
  • A potential radio-sensitizer that may improve outcomes following radiotherapy
  • A side effect of abiraterone acetate, and its management
  • Bisphosphonate therapy and osteonecrosis of the jaw or ONJ … READ MORE …
