För att undersöka djup ventrombos används kompressionsultraljud och för lungemboli spiraldatortomografi (DT-angiografi) eller lungskintigrafi.
Diagnostic tests for thromboembolic disease include (a) the D-dimer assay, which has a high sensitivity but poor specificity in this setting (,3), (b) ventilation-perfusion scintigraphy, which has a high sensitivity but ve… The authors conclude that CT is an important modality for confirming the presence of pulmonary septic emboli even when conventional chest radiographs remain negative. In the proper clinical setting, characteristic CT features of septic emboli can suggest the correct diagnosis. Systemic air embolism (air in the systemic arterial circulation) is considered a rare complication of CT-guided percutaneous lung biopsy. Though often self-limiting, it can lead to disastrous, even fatal complications when the air embolus reaches the brain or coronary arteries. Röntgen Helsingborg 1997-2016 Comments are closed. Röntgen Helsingborg- Septic embolism in patient with multiple pulmonary nodules and extrapulmonary focus of infection Axial CECT shows multiple peripheral thick-walled cavitary nodules from septic emboli. Axial CECT coronal reconstruction shows distribution and number of cavitary nodules.

Negative computed tomography ”Low” sensitivity •Bilateral ultrasound on all negative CT (80%) • Fedullo & Tapson NEJM 2003;349:1247-56 •Routine CT venography (100%) CT-angiografi anses vara tillräcklig för en LE-diagnos om resultatet visar en propp i lungartärernas segment 1. Kompressionsultraljud av ben. Att göra benultraljud innan en CT kan vara ett alternativ för patienter som har relativa kontraindikationer för CT (t.ex. njursvikt, graviditet eller allergi mot kontrastmedel) 1.
Förstorad höger kammare på CT hos patienter med lungemboli indikerar en 5ggr så hög mortalitetsrisk inom de närmsta 30 dagarna som lungemboli utan förstorad höger kammare. - Differentialdiagnostik: Visar parenkymförändringar som kan vara alternativa förklaringar till patientens symptom: Pneumoni, emfysem, lungfibros, massa i lungparenkymet, aortapatologi.
In most cases, radiographic changes were nonspecific. In comparison, on CT a combination of specific signs could be identified in all patients.

Many different types of tissues—including the lungs, heart, bones, soft tissues, muscles, and blood vessels—can be seen. When PE is suspected, contrast dye (usually iodine dye) is administered through a vein to make the blood vessels stand out. 2008-04-01 arteries. For each pig, 5 type-A (ø3.5 × 8 mm) and 5 type-B (ø2.5 × 6 mm) emboli were injected through a catheter with the distal tip located in the inflow tract of the right atrium. After obtaining precontrast and postcontrast CT data during a single breath-hold using a 4-slice multidetector CT, perfusion images were generated by data subtraction.

In some cases, contrast material is given intravenously during the CT scan to outline the pulmonary arteries. Ventilation-perfusion scan (V/Q scan)
Purpose: Our purpose is to describe the CT findings in pulmonary fat embolism syndrome (FES). Method: Chest radiographs and CT scans of six patients with pulmonary FES were reviewed.

At the other end of the clinical spectrum, in patients with a low probability of PE, but a positive CT pulmonary angiography is the principal imaging test to assess for suspected pulmonary emboli.
