Screening of illegal intracorporeal containers ("body packing"): is abdominal radiography sufficiently accurate?
Abdominal radiography is mainly limited by low sensitivity when compared with low-dose CT in the screening of people suspected of carrying drug packets. Low-dose CT is an effective imaging alternative to abdominal radiography.
Metastatic prostate cancer remains incurable. Therefore detection of organ-confined and potentially curable disease, is crucial. Though PSA has led to earlier detection, this study emphasises the importance of clinical examination, illustrating a normal PSA cannot eliminate the possibility of cancer. DRE and PSA should be interpreted as being collaborative, not competitive.
