PURPOSE Compare the right ventricle to left ventricle (RV/LV) diameter ratio obtained from axial pulmonary CT angiograms (CTPA) with those derived from automatically generated 4-chamber (4-CH) reformats in patients with suspected pulmonary embolism (PE). METHODS In this institutional review board-approved study we included 120 consecutive non ECG-gated CTPA from 3 institutions (mean age 60 ± ...

OBJECTIVES Contrast-enhanced computed tomography (CT) provides essential cross-sectional imaging data in patients with suspected pleural malignancy (PM). The performance of CT in routine practice may be lower than in previously reported research. We assessed this relative to 'real-life' factors including use of early arterial-phase contrast enhancement (by CT pulmonary angiography (CTPA)) and n...

AIM To examine the number and nature of investigations performed for suspected pulmonary embolism (PE) in a large teaching hospital and the change in incidence and severity of PE over a decade. MATERIALS AND METHODS In this retrospective study, all patients investigated for suspected PE using computed tomography pulmonary angiography (CTPA) or lung scintigraphy during 10 years to March 2012 w...

OBJECTIVES To evaluate the image quality and radiation dose of submillisievert standard-pitch CT pulmonary angiography (CTPA) with ultra-low dose contrast media administration in comparison to standard CTPA. MATERIALS AND METHODS Hundred patients (56 females, 44 males, mean age 69.6±15.4 years; median BMI: 26.6, IQR: 5.9) with suspected pulmonary embolism were examined with two different prot...

BACKGROUND Our purpose was to evaluate the effectiveness of different kilovolt (kV) uses in computed tomography pulmonary angiography (CTPA) in the diagnosis of pulmonary thromboembolism (PTE). We also aimed to establish the optimal kV value and investigate the possibility of obtaining appropriate imaging quality with minimal radiation dose. MATERIAL AND METHODS We compared 120, 100, and 80 k...

OBJECTIVES The objective of this study was to determine whether automated quantification of lung perfused blood volume (PBV) in dual-energy computed tomographic pulmonary angiography (DE-CTPA) can be used to assess the severity and regional distribution of pulmonary hypoperfusion in emphysema. MATERIALS AND METHODS We retrospectively analyzed 40 consecutive patients (mean age, 67 [13] years) ...

AIM To provide imaging data and report associations between human immunodeficiency virus (HIV), tuberculosis (TB) and pulmonary embolism (PE) in a South African population that underwent computed tomography pulmonary angiography (CTPA) for suspected PE. METHODS A validated Qanadli severity scoring system for PE was used for 164 CTPA scans, and parenchymal, pleural and cardiovascular complicat...

BACKGROUND The requirement of postoperative bedridden and immobilization renders neurosurgical patients with higher risk of deep vein thrombosis (DVT), then more vulnerable for pulmonary thromboembolism (PTE). But silent pulmonary thromboembolism (SPTE) can be the very early stage of any typical form of PTE, its diagnosis and management is therefore critical in neurosurgical departments. Howeve...

The septal angle, an angle between the interventricular septum and the line connecting the sternum midpoint and thoracic vertebral spinous process, as measured by computed tomographic pulmonary angiography (CTPA), has been observed to be increased in patients with pulmonary hypertension (PH), but its meaning remains unclear. The aim of this study was to investigate the potential role of the sep...

Introduction Computed tomography pulmonary angiography (CTPA) is the reference investigation of choice to diagnose embolism (PE). Nevertheless, use CTPA should be weighed against its risks, such as radiation and contrast-induced nephropathy. We aim assess yield in diagnosing PE at a tertiary centre Malaysia. also identify predictive factors associated with this cohort. Methods This was cross-se...
