Abstract

PURPOSE: The purpose of our study was to demonstrate a new visualization method (local maximum intensity projection; LMIP) that can clearly depict densitometric as well as geometric information in vascular visualization from 3D data such as obtained from MR and CT angiography. METHOD: LMIP is an extended version of maximum intensity projection (MIP). However, LMIP differs from MIP in that the latter method selects the maximum value along an optical ray, whereas LMIP selects the first local maximum value encountered that is larger than a preselected threshold value along an optical ray from a viewpoint in the viewing direction. RESULTS AND CONCLUSION: Examples are presented in which LMIP is used to visualize renal vessels from CT angiography data and cerebral vessels in the vicinity of an aneurysm from phase-contrast MR angiography data. We demonstrate that LMIP can clearly depict geometric information, as shaded surface display does, and densitometric information, as is done by volume rendering, in a straightforward and objective manner.

Transhepatic vascular access for diagnostic and interventional procedures: techniques, outcome, and complications.

Early or multiple cardiac catheterizations may result in occlusion of the femoral veins prohibiting their use. The internal jugular or sub-clavian approach may be an appropriate alternative. However, these approaches may not be suitable in patients with surgical interruption of the superior vena cava. In other patients, they may not allow easy access to certain areas of the heart. The transhepatic approach is an important alternative route for performing cardiac catheterization and interventions. Depending on the planned procedure, it may be the preferred route to perform the cardiac catheterization even in the presence of patent femoral veins. The indications, technical details and potential complications of this approach are discussed.

Embolization for a bleeding pelvic fracture in a patient with persistent sciatic artery.

Emergency embolization for a bleeding pelvic fracture was performed in a patient with persistent sciatic artery, a rare anatomic variation in which the internal iliac artery continues to the popliteal artery. Successful hemostasis was achieved without complications by means of selective catheterization into each branch of the internal iliac artery. Awareness of this unusual vascular anatomy is critically important to avoid serious complication of emergency embolization.
