Blunt cerebrovascular injuries (BCVI) can cause ischemic stroke and are associated with high mortality rates. These injuries may have an initial silent course and if recognized in a timely fashion can be treated before neurologic deficit occurs. This has led to the growing implementation of aggressive screening programs to detect and thereby treat BCVI early, before onset of symptoms. Digital subtraction angiography is the diagnostic reference standard for diagnosing BCVI. However, in recent years, there has been a renewed interest in the use of noninvasive techniques, such as multidetector computed tomography angiography (MDCTA) for the evaluation of these patients. The accuracy of MDCTA with respect to digital subtraction angiography is not completely elucidated; however, MDCTA shows a level of accuracy sufficient to serve as an initial screening examination for blunt cerebrovascular injuries.

Disorders of the pulmonic valve (PV) receive considerably less attention than other forms of valvular heart disease. Due to the dramatically improved survival of children with congenital heart disease over the last 5 decades, there has been a steady increase in the prevalence of adults with congenital heart disease, which necessitates that clinicians become familiar with the anatomy and the evaluation of right ventricular outflow tract and PV anomalies. A multimodality imaging approach using echocardiography, cardiac computed tomography, and magnetic resonance imaging is essential for a comprehensive evaluation of the anatomy and function of the right ventricular outflow tract, PV, and supravalvular region.

Background: The majority of functional ischemia tests in patients with suspected chronic coronary syndromes (CCS) yield normal results. Implementing gatekeepers for patient preselection, such as pretest probability (PTP) and/or coronary artery calcium score (CACS), could reduce the number of normal scan results, radiation exposure and costs. However, the efficacy and safety of these approaches remain unclear.

Background: Pediatric lumbar spondylolysis (LS) is common in junior and senior high school athletes. Lower LS (L4-L5 level) is more common in children, and upper LS (L1-L3 level) is relatively rare; therefore, the pathogenesis of upper LS remains unclear.
Purpose: To elucidate the mechanisms of upper LS by identifying and comparing characteristics between upper and lower LS cases.

Pulmonary vein isolation (PVI) represents the cornerstone of paroxysmal (PAF) and persistent atrial fibrillation (PsAF) ablation. Impedance values provide insights on tissue conductive properties. Consecutive patients undergoing PAF and PsAF ablation were prospectively enrolled.
