'''As the use of computed tomography (CT) scans, which are expensive and result in considerable radiation exposure to the patient, continues to increase, communication between physicians and radiologists remains vital to explain the clinical context for the ...'

'''Patients who receive cardiac positron emission testing (PET) imaging instead of single photon emission computed tomography (SPECT) scan experienced a significant increase in the detection of severe obstructive coronary artery disease, according to ...'

'''Researchers report a technique for high-resolution biological imaging using X-ray computed tomography (CT). X-ray CT allows noninvasive 3D reconstruction of the external and internal structures of a sample, but conventional laboratory-based CT equipment ...'

'''Computed tomography colonography (CTC), also known as virtual colonoscopy, offers a noninvasive alternative to traditional (optical) colonoscopy for detection of precancerous polyps. The technology has been around for over 20 years, and numerous studies ...'

'''Diagnostic examinations of the head (head scans) and of other parts of the body (body scans) performed by computerized tomography (CT) scanners are covered if medical and scientific literature and opinion support the effective use of a scan for the ...'

'''New research from Johns Hopkins School of Medicine reveals a high value of scans which could lead to future change of reimbursement policies for follow-up positron emission tomography/computed tomography (PET/CT) studies in lung cancer. The study, ...'

'''Over the last few decades, there has been a dramatic increase in the availability and application of tests that use ionizing radiation to take images of the body. These tests include computed tomography, or CT, scans and nuclear medicine exams that ...'

'''Investigators of the COSMOS (Continuous Observation of SMOking Subjects) study show good compliance and patient survival outcomes using a 5-year low-dose computed tomography (LDCT) screening protocol in individuals at high-risk of developing lung cancer. ...'

'''Among patients with a certain type of colorectal cancer with limited spread to the liver, imaging using positron emission tomography and computed tomography (CT) before surgery did not significantly change the surgical treatment of the cancer, compared ...'
