Conventional radiography only provides a measure of the X-ray attenuation caused by an object; thus, it is insensitive to other inherent informative effects, such as refraction. Furthermore, conventional radiographs are degraded by X-ray scatter that can obscure important details of the object being imaged. The novel X-ray technology diffraction-enhanced imaging (DEI) has recently allowed the v...

A 77-year-aged male patient without a remarkable medical history underwent colonoscopy because of chronic constipation and colon cancer family history. Colonoscopy failed at the 50 cm from the anal verge by the presence of bleeding from the proximal site of the colon. While retracting endoscope adipose tissue of retroperitoneum appeared. The lumen of the colon was collapsed (blue arrow) and imm...

BACKGROUND Radiological examinations are commonly requested for patients to aid clinical diagnosis. However, many doctors do not realise how much radiation dosage their patients are exposed to during radiological investigations. This study aims to assess and compare the knowledge of radiologists and non-radiologists about radiation doses of common radiological investigations. METHODS A prospe...

When considering chronic opioid therapy (COT) for chronic noncancer pain, it has been proposed that it is prudent to contemplate 4 questions which may be useful and influence medical decision making (1): 1. What is the conventional practice? 2. Are there reasonable alternatives to COT? 3. What is the risk of adverse events? 4. Is the patient likely to be a responsible drug-taker? Question 4 – (...
