There is no advantage to adding CT of the abdomen and pelvis to a basic screening protocol for occult malignancy in patients with unprovoked VTE.

Ethical Use of Diagnostic Technology: Balancing What's New and What's Necessary [Curbside Consultation]
This case boils down to being realistic about what new screening tools and techniques can and can't do, and understanding their actual value in diagnoses. I'd argue that it is not unethical to accommodate a patient's requests, as long as the physician's approach to the patient, the pathology, the te...

Ultrasound-Guided Steroid Injections for Shoulder Pain [Cochrane for Clinicians]
Ultrasound-guided glucocorticoid injection for shoulder pain provides no advantage over landmark-guided or intramuscular injection in terms of pain, function, range of motion, or safety when measured within a six-week follow-up period. However, the small sample size of this review means that a clinically significant benefit cannot be ruled out.
The use of CT imaging has risen dramatically in the past two decades, and there is substantial evidence that it is overused. One concern is that the harms and risks of CT have been underestimated and poorly understood, and are not often discussed with patients. These harms should be balanced with the potential diagnostic benefits.
Family physicians often must determine the most appropriate diagnostic tests to order for their patients. It is essential to know the types of contrast agents, their risks, contraindications, and common clinical scenarios in which contrast-enhanced computed tomography is appropriate. Many types of c...
Photo Quiz presents readers with a clinical challenge based on a photograph or other image.
Risks of diagnostic imaging include cancer from radiation exposure and nephrogenic systemic fibrosis. The increase in volume of imaging between 1980 and 2006 has led to a sixfold increase in annual per capita radiation exposure. It is predicted that 2 percent of future cancers will be caused by radi...
Is coronary CTA good enough to allow for the safe discharge of low- to intermediate-risk patients with chest pain? Coronary CTA and standard care were equally effective at identifying a low-risk population. The test saved seven hospital hours, but at the expense of radiation exposure, higher costs, and more use of resources.
CT has substantially advanced medical care through improved diagnosis, but its use comes with potential harms, including cancer risk from radiation; detection of incidental findings that may lead to additional and often unnecessary diagnostic testing and treatment; and accidental radiation overdose....
