OBJECTIVE: We sought to perform a systematic review and meta-analysis of published CT colonography (CTC) studies assessing lesion detection in senior-age (≥ 65 years old) cohorts. MATERIALS AND METHODS: We conducted a systematic review of CTC studies published between January 1994 and August 2017 containing data on senior-age adults. The primary endpoint was the CTC-positive rate for large colorectal polyps (≥ 10 mm) and masses. Secondary endpoints included lesions ≥ 6 mm, proven advanced neoplasia, and colorectal cancer (CRC)...

OBJECTIVE: Motion artifact can reduce the diagnostic accuracy of coronary CT angiography (CCTA) for coronary artery disease (CAD). The purpose of this study was to compare the diagnostic performance of an algorithm dedicated to correcting coronary motion artifact with the performance of standard reconstruction methods in a prospective international multicenter study. SUBJECTS AND METHODS: Patients referred for clinically indicated invasive coronary angiography (ICA) for suspected CAD prospectively underwent an investigational CCTA examination free from heart rate-lowering medications before they underwent ICA...

OBJECTIVE: The purpose of this study was to determine whether individual radiologists are predictive of important relevant health outcomes among emergency department (ED) patients undergoing abdominopelvic CT for right lower quadrant pain. MATERIALS AND METHODS: This single-institution retrospective cohort study included 2169 patients undergoing abdominopelvic CT for right lower quadrant pain in the ED from February 1, 2012, through August 31, 2016. CT examinations were interpreted by 15 radiologists (four emergency, 11 abdominal) who each reported on more than 70 CT examinations in the cohort...

OBJECTIVE: The objective of this article is to propose a Warthin tumor (WT) score to distinguish WTs from other parotid tumors. MATERIALS AND METHODS: The study included 78 patients with 92 histologically proven parotid tumors, including 42 WTs, 30 pleomorphic adenomas (PMAs), and 20 carcinomas. Echo-planar DW images were acquired. The WT score, which comprised the mean apparent diffusion coefficient (ADCM ) and the SD of the ADC (ADCSD ) of tumors, patient age, and patient sex, was used to predict WTs...

OBJECTIVE: Because of the ubiquitous use of radiologic imaging, particularly with CT, the detection of focal hepatic calcifications has increased. Calcifications can be seen in cystic and solid masses associated with both benign and malignant causes, pseudomasses, and miscellaneous pathologic abnormalities. CONCLUSION: These calcifications can manifest in various patterns, recognition of which can increase specificity for various diagnoses. In this article, we review a wide range of calcified hepatic pathologic abnormalities at CT and propose an approach for diagnosis...

OBJECTIVE: This commentary discusses research examining comparisons of locoregional therapy with systemic therapy for unresectable hepatocellular carcinoma (HCC). CONCLUSION: Comparison of patient outcomes after locoregional or systemic therapy for HCC is confounded by selection bias, wherein patients chosen for locoregional therapy usually have better underlying liver function that may contribute to the observed longer survival.

OBJECTIVE: The purpose of this study was to retrospectively determine whether the egg-and-banana sign, defined as the visualization of the main pulmonary artery (PA) at the level of the aortic arch, is a sensitive and specific diagnostic marker for pulmonary hypertension. MATERIALS AND METHODS: A total of 186 patients who, between January 2014 and July 2017, received right heart catheterizations and underwent CT studies that included the aortic arch within 140 days of catheterization were evaluated in this retrospective study...

OBJECTIVE: The question of benefits versus harms of breast cancer screening for women younger than 50 years old has been the subject of debate. We investigate if the addition of tomosynthesis to mammography improves screening performance outcomes for women in this age group. MATERIALS AND METHODS: Screening performance for 59,921 patients (41,542 digital mammography and 18,379 tomosynthesis) younger than 50 years old was collected from a community-based screening network from January 1, 2015, to December 31, 2015...

OBJECTIVE: Renal cell carcinoma (RCC) has a propensity to metastasize to the chest, with the lungs being the most common distant metastatic site. The histologic subtype of RCC has implications for prognosis. CONCLUSION: Significant advances have been made in the management of metastatic RCC, both in systemic and locoregional therapies. The aim of this article is to review appearances of intrathoracic metastases from RCC and to discuss treatment considerations.

OBJECTIVE: We outline the concept of intraductal papillary neoplasm of the bile duct (IPNB), discuss the morphologic features of IPNB and the differential diagnoses, and describe the radiologic approaches used in multidisciplinary management. CONCLUSION: The concept of IPNB has been evolving. Because the imaging features of IPNB can be variable, different mimickers according to IPNB subtype can be considered. A multimodality approach is essential to obtain an optimal diagnosis and establish treatment plans...

OBJECTIVE: The purpose of this study is to evaluate the clinical effect of liver stiffness measured using MR elastography (MRE) in patients with cholestasis due to biliary obstruction. MATERIALS AND METHODS: In this retrospective study, 69 consecutive patients with no history of diffuse liver disease who underwent pancreaticobiliary imaging with MRE were included.

OBJECTIVE: The purpose of this study was to determine the cost-effectiveness of landmark-based and image-guided intraarticular steroid injections for the initial treatment of a population with adhesive capsulitis. MATERIALS AND METHODS: A decision analytic model from the health care system perspective over a 6-month time frame for 50-year-old patients with clinical findings consistent with adhesive capsulitis was used to evaluate the incremental cost-effectiveness of three techniques for administering intraarticular steroid to the glenohumeral joint: landmark based (also called blind), ultrasound guided, and fluoroscopy guided...

OBJECTIVE: Dynamic CT is increasingly used for preoperative localization of parathyroid adenomas, but concerns remain about the radiation effective dose of CT compared with that of 99m Tc-sestamibi scintigraphy. The purpose of this study was to compare the radiation dose delivered by three-phase dynamic CT with that delivered by 99m Tc-sestamibi SPECT/CT performed in accordance with our current protocols and to assess the possible reduction in effective dose achieved by decreasing the scan length (i...

OBJECTIVE: The objective of our study was to evaluate the diagnostic performance of CT in the identification of anastomotic leaks. MATERIALS AND METHODS: This was a study of patients who underwent bowel surgery and a subsequent postoperative CT examination performed specifically for investigating for an anastomotic leak. The study group included patients with surgically confirmed anastomotic leaks (n = 59), and the control group included patients without anastomotic leaks (n = 48) confirmed by either repeat surgery or uneventful clinical follow-up for at least 6 months...
