Many congenital heart conditions that were previously considered to be inoperable are now able to be corrected surgically. As a result, a more accurate and refined "surgical diagnosis" than that offered by conventional angiography has been sought. Axial cineangiography is invaluable in establishing a specific diagnosis in such cases.
Cineangiographic axial techniques were designed to overcome the limitations of conventional angiography in the diagnosis of congenital heart disease. Two basic patient (or equipment) maneuvers are involved; 1) long axis of the heart is aligned perpendicular to the X-ray beam, and 2) rotation of patient results in the heart being radiographically sectioned(More)
The value of axial cineangiography in several forms of congenital heart disease serves as an illustrated supplement to Section I. These techniques visualize defects in the entire ventricular and atrial septum. In persistent atrioventricular (A-V) canal, it is possible to visualize all parts of both septa, status of the A-V valves (two valves versus a common(More)
Digital mammography can potentially improve mammography image and interpretation quality. On-line interpretation from a workstation may improve interpretation logistics and increase availability of comparison images. Interpretation of eight 4k- x 5k-pixel mammograms on two to four 2k- x 2.5k-pixel monitors is problematic because of the time spent in(More)
Mediastinal fibrosis can present with a multitude of symptoms, most commonly cough, dyspnea and hemoptysis. We describe a case of mediastinal fibrosis secondary to histoplasmosis, which presented with both superior vena cava syndrome (SVCS) and hemoptysis. Our patient was successfully treated with bronchial artery embolization followed by SVC stent(More)
Radiofrequency ablation (RFA) is well described in the treatment of primary hepatic malignancies and colorectal carcinoma hepatic metastases. A known complication of RFA is the development of hepatic abscess. The management of hepatic abscesses subsequent to RFA for metastatic disease is not well described. A 49-year-old female with pancreatic(More)
To compare the relative merits of conventional and axial RAO/LAO angiography, we performed biplane left ventricular (LV) cineangiograms in 36 patients in both the conventional 30-degree RAO/60-degree LAO projection and in the axial 45-degree RAO/60-degree LAO/25-degree cranial projection, in random sequence. LV volumes were calculated by a computerized(More)
