Summary: The study found that the overall frequency of IPE in oncologic patients was 3.36%, with the highest frequency in prostate cancer, hepatobiliary carcinoma, and pancreatic cancer. In contrast, tumors of male reproductive organs and hematological diseases had lower frequencies of IPE.

Summary: This study aims to examine the diagnostic performance of CT of the pulmonary artery (CTPA) as a potential first-choice imaging modality in patients with pulmonary arterial hypertension and suspected chronic thromboembolic pulmonary hypertension (CTEPH). A systematic review and meta-analysis were conducted to evaluate the diagnostic performance of CTPA in adult patients. The results indicate that CTPA has high sensitivity and specificity in the detection of CTEPH.

Summary: European emergency department studies showed a higher prevalence of PE and higher diagnostic yield from CTPA compared to North America, despite a higher frequency of CTPA use among European patients. This supports the hypothesis that North American ED patients tested for PE have a lower risk of PE compared to European patients.

Summary: The diagnostic performance of dual-energy computed tomography (DECT) with post-processing techniques was evaluated for acute pulmonary embolism (PE). The results showed that both dual-energy and single-energy CT can comparably be used for the detection of acute PE.

Summary: This study evaluated the feasibility and accuracy of using CT pulmonary angiography (CTPA) for diagnosing acute heart failure (HF) in emergency department patients. The results showed that both HUratio and HUdiff had a high sensitivity for diagnosing HF, indicating their potential as viable diagnostic markers.

Summary: In a selected, high-prevalence population, VP-DECT is considered an accurate imaging tool for diagnosing PE compared to CTPA. The sensitivity of VP-DECT images in per-patient analysis was 90.0%, with 100% specificity; while in per-lobe analysis, sensitivity ranged from 100% for the right lower lobe to 50% for the left upper lobe.

Summary: This study aimed to describe the radiological features of chronic thromboembolic pulmonary disease (CTEPD) and compared them with chronic thromboembolic pulmonary hypertension (CTEPH) patients. The results showed significant differences in vascular obstruction, hypoperfusion, mosaic attenuation, and signs of pulmonary hypertension between the two groups, suggesting that the absence of peripheral microvascular disease may be the reason for the absence of pulmonary hypertension in CTEPD patients.

Summary: CTPA findings can predict 30-day mortality of patients with APE in the Emergency Department, particularly the quantification of right ventricular strain, which is associated with troponin I levels and echocardiographic signs of right-heart dysfunction. The study suggests that a dilated coronary sinus may have additional prognostic value in predicting mortality.

Summary: PE is a common complication in COVID-19 patients, but there is a lack of clear guidelines for diagnosing PE. While many COVID-19 patients may have indications for CTPA, only a small percentage actually undergo this examination, and there are no significant clinical differences between those who do and those who do not.

Summary: This study evaluated the utility of perfusion defects on dual-energy CT angiograms in assessing the clinical severity of pulmonary embolism, finding significant correlations between the presence of perfusion defects and parameters evaluating PE severity. Presence of a perfusion defect and higher perfusion defect score were associated with lower survival rates.

Summary: This study evaluated the relationship between CAC on non-ECG-gated CTPA and short-term mortality in patients with acute PE. The results showed that CAC is common and associated with mortality in these patients. Visual assessment of CAC may be an easy tool for early risk stratification.

Summary: This study aimed to estimate the diagnostic yield of CTPA in clinically suspected PE patients at a tertiary care hospital in Saudi Arabia. The study found that CTPA had a higher positive detection rate for PE among clinically suspected cases than its published diagnostic yield. Adequate clinical evaluation when selecting patients for CTPA is emphasized to minimize unjustified exposure of the patients to radiation and contrast.

Summary: The objective of this study was to define a safe strategy to exclude pulmonary embolism (PE) in COVID-19 outpatients without performing CT pulmonary angiogram (CTPA). The study evaluated COVID-19 outpatients from 15 university hospitals who had undergone a CTPA. Different PE rule-out strategies, including D-Dimer tests with different thresholds, the revised Geneva and Wells scores, and a COVID-19 PE prediction model, were compared. The results showed that D-Dimer > 500 mu g/l and the age-adjusted D-Dimer level, as well as the revised Geneva and Wells scores, had good performance in excluding PE.

Summary: This study evaluates the diagnostic value of computed tomography (CT) in pulmonary hypertension. Through literature search and meta-analysis, it is found that CT examination of pulmonary artery diameter/aortic artery hypertension has good sensitivity and specificity and can be used in clinical applications.

Summary: By combining multiple CT parameters, a simple tool was developed for individualized risk assessment of deterioration in non-high-risk acute PE patients at admission. The right-to-left ventricular diameter ratio in the 4-chamber view and pulmonary vein filling abnormality were found to be related to deterioration risk. The developed nomogram had AUROC values of 0.91 in the derivation cohort and 0.89 in the validation cohort.
