Examples include apical tuberculous fibronodular changes, symmetric bilateral ground glass opacities in pneumocystis jiroveci pneumonia, cavitary filling defects
of aspergillomas, hepatic and pulmonary hydatid cysts, and pleuroparenchymal changes in paragonimiasis, all of which may calcify, rarely in some cases.
Thirty patients (86%) had an abnormal ductogram that was characterized as a filling defect
(n = 20), cutoff sign (n = 5), or ductal dilatation (n = 5).
B) CT angiography showing prominent proximal thombus in the lower and upper pole second order branches and multiple distal filling defects
1 software, R2's Pulmonary Artery Patency Exam (PE(TM)) tool features expanded software capability by providing volume calculations for filling defects
, which can help the physician's decision making.
Delayed overhead images from an upper gastrointestinal (GI) series demonstrated a dilated proximal jejunum and multiple ovoid filling defects
occluding the bowel lumen (Figure 1B).
2: Contrast-enhanced axial abdominal computed tomography scan: On the delayed phase, a new 20x7x12-mm filling defect
in left renal pelvis is shown (arrow).
Two-dimensional and Doppler venous ultrasound of the right upper extremity showed an intraluminal filling defect
within the right subclavian vein (Figure 1A) extending into the right axillary (Figure 1B) and basilic (Figure 1C) veins.
The second clearance is for the Filling Defect
Indicator software module, designed to help physicians visualize and evaluate filling defects
in pulmonary arteries, such as pulmonary emboli.
Ultrasound and computed tomography (CT) studies revealed a mottled filling defect
in the stomach that extended into the third part of the duodenum.
The ImageChecker CT software package with Filling Defect
Indicator (FDI) is used during the review of contrast-enhanced MDCT images of the chest.
CT revealed a left ovarian vein filling defect
, which extended into the pelvis with multiple filling defects
in the left and right ovarian veins.
Target lesions or true-positive CAD marks include any vascular filling defect
In acute PE, an embolus is most often seen as an intraluminal filling defect
of soft tissue attenuation with the proximal convex aspect of the clot outlined by contrast and the contrast column forming an acute angle with the vessel wall (Figure 6).
Figure 6 provides an example of a peripheral intraluminal filling defect
that formed an acute angle with the arterial wall.
26) Following the terminal ileum into the colon is helpful to confirm that the filling defect
is the ileocecal valve.
