Spatial and spectral information are essential sources of in remote sensing applications, the fusion panchromatic multispectral images effectively combines advantages both. Due to existence two main classes methods—component substitution (CS) multi-resolution analysis (MRA), which have different advantages—mixed approaches possible. This paper proposes a algorithm that generalized intensity–hue...

Preoperative imaging is essential for abdominal perforator flap breast reconstruction because it allows for preoperative perforator selection, resulting in improved operative efficiency and flap design. The benefits of visualizing the vasculature preoperatively also extend to gluteal artery perforator flaps. Initially, our practice used computed tomography angiography (CTA) to image the gluteal...

AIM To review the published literature comparing the diagnostic accuracy of magnetic resonance angiography (MRA) with and without gadolinium in diagnosing renal artery stenosis, using catheter angiography as reference. MATERIALS AND METHODS A meta-analysis was performed of English language articles identified by computer search using PubMed/MEDLINE, followed by extensive bibliography review f...

A novel many-valued decomposition within the framework of lossless Reconstructability Analysis is presented. In previous work, Modified Recontructability Analysis (MRA) was applied to Boolean functions, where it was shown that most Boolean functions not decomposable using conventional Reconstructability Analysis (CRA) are decomposable using MRA. Also, it was previously shown that whenever decom...

Background Navigator gated coronary MRA is highly time inefficient as the data collection duty cycle (DC) is only 2% [1]. Here, we report a new, dynamic self-navigated coronary MRA technique with isotropic spatial resolution that a) further improves DC by continuously acquiring image data without ECG triggering and that b) enables retrospective, flexible, and individual selection of the acquisi...

BACKGROUND AND PURPOSE Systematic assessment of brain and head and neck tumors with 4D-CE-MRA at 3T has not been investigated. The purpose of this study was to test the hypothesis that 4D-CE-MRA at 3T can replace DSA in the identification of feeding arteries and tumor stain to plan interventional procedures in hypervascular brain and head and neck tumors. MATERIALS AND METHODS Fifteen consecu...

OBJECTIVES Simultaneous Non-contrast Angiography and intraPlaque hemorrhage (SNAP) technique was recently proposed for joint MRA and intraplaque hemorrhage (IPH) imaging. The purpose of this study is to validate SNAP's MRA performance in patients with suspected intracranial artery disease. METHODS SNAP and time-of-flight (TOF) techniques with matched field of view and resolution were applied ...
