Radiologists have come to expect rising demand for CT, which is why anecdotal reports of sudden and dramatic falls in CT volumes have sent a shudder through the community. All the more alarming is that the rumored drop-offs are coming at the request of patients who want nothing to do with CT because they fear its radiation will someday cause cancer. Instead they reportedly are demanding ultrasound or MRI because neither has ionizing radiation -- never mind that neither is indicated, nor, particularly in the case of ultrasound, has much chance of providing useful information.
