PURPOSE The authors hypothesize patient facial affect may influence clinician pretest probability (PTP) estimate of cardiopulmonary emergency (CPE) and desire to order a computerized tomographic pulmonary angiogram (CTPA). METHOD This prospective study was conducted at three Indiana University-affiliated hospitals in two parts: collecting videos of patients undergoing CTPA for suspected acute...

Recent advances in the management of patients with suspected VTE have both improved diagnostic accuracy and made management algorithms safer, easier to use and well standardised. These diagnostic algorithms are mainly based on the assessment of clinical pretest probability, D-dimer measurement and imaging tests, mainly represented by compression ultrasound (CUS) for suspected DVT and computed t...

Background: Lowering the amount of iodinated contrast material and tube voltage may increase pulmonary artery opacification thrombus identification without compromising picture quality. Objectives: To explore efficiency using lower a medium dose for conducting computed tomography angiography (CTPA) aiming to its accuracy in detecting thromboembolism (PTE). Subjects Methods:100 patients schedule...

BACKGROUND The correlation between normal cardiac chamber linear dimensions measured during retrospective coronary computed tomographic angiography as compared to transthoracic echocardiography using the American Society of Echocardiography guidelines is not well established. METHODS We performed a review from January 2005 to July 2011 to identify subjects with retrospective electrocardiogram...

A 25-year-old male presented to the emergency department with 1 week of progressive right-sided chest pain. The pain was sharp, radiated to the back, and worse with deep inspiration. He denied dyspnea and leg pain or swelling. The patient’s medical history was remarkable for a lower extremity deep vein thrombosis diagnosed 6 months prior. He’d selfdiscontinued anticoagulant therapy 2 months pri...

Background It is uncertain whether we can predict contrast-induced nephropathy (CIN) after CT pulmonary angiography (CTPA). This study compared the ability of a validated CIN prediction score with the Pulmonary Embolism Severity Index (PESI) in predicting CIN after CTPA. Methods This cohort study involved critically ill adult patients who required a CTPA to exclude acute pulmonary embolism (P...

Pulmonary embolism (PE) is a potentially life threatening condition requiring adequate diagnosis and treatment. Computed tomography pulmonary angiography (CTPA) is excellent for including and excluding PE, therefore CT is the first-choice diagnostic imaging technique in patients suspected of having acute PE. Due to its wide availability and low invasiveness, CTPA tends to be overused. Correct i...

Abstract Background Pulmonary embolism (PE) is one of the known sequels COVID-19 infection. We aimed to assess incidence PE in patients with infection and evaluate relationship between CT severity disease laboratory indicators. This was a retrospective study conducted on 96 proved by positive PCR who underwent pulmonary angiography (CTPA) calculation Available patients’ complaint data at time C...
