Visualization of tubular structures such as blood vessels is an important topic in medical imaging. One way to display tubular structures for diagnostic purposes is to generate longitudinal… Expand
CT artifacts: Causes and reduction techniques
Artifacts are commonly encountered in clinical CT and may obscure or simulate pathology. There are many different types of CT artifacts, including noise, beam hardening, scatter, pseudoenhancement,… Expand
Incomplete endograft apposition to the aortic arch: bird-beak configuration increases risk of endoleak formation after thoracic endovascular aortic repair.
PURPOSE To determine the clinical importance of the bird-beak configuration after thoracic endovascular aortic repair (TEVAR). MATERIALS AND METHODS The institutional review board approved this… Expand
Computed tomography—old ideas and new technology
Several recently introduced ‘new’ techniques in computed tomography—iterative reconstruction, gated cardiac CT, multiple-source, and dual-energy CT—actually date back to the early days of CT. We… Expand
Radiographically occult scaphoid fractures: value of MR imaging in detection.
PURPOSE To evaluate the diagnostic value of magnetic resonance (MR) imaging in patients with clinical suspicion of scaphoid fractures and normal initial plain radiographs. MATERIALS AND METHODS MR… Expand
Optimal vascular and parenchymal contrast enhancement: the current state of the art.
A fundamental understanding of early arterial and parenchymal contrast medium (CM) dynamics is the basis for the design of CT scanning and injection protocols for state-of-the-art cardiovascular and… Expand

OBJECTIVE The aim of our study was to assess the evolution of pulmonary CT findings in cystic fibrosis patients. MATERIALS AND METHODS Serial CT examinations were performed in four different… Expand
Mathematical analysis of arterial enhancement and optimization of bolus geometry for CT angiography using the discrete fourier transform.
PURPOSE The goal of this work was to develop a clinically applicable mathematical algorithm to analyze and optimize individual arterial enhancement in CT angiography (CTA). METHOD Assuming a… Expand
CT angiography of peripheral arterial disease.
Lower-extremity computed tomographic (CT) angiography (ie, peripheral CT angiography) is increasingly used to evaluate patients with peripheral arterial disease. It is therefore increasingly… Expand
Improved uniformity of aortic enhancement with customized contrast medium injection protocols at CT angiography.
PURPOSE To compare the uniformity of aortoiliac opacification obtained from uniphasic contrast medium injections versus individualized biphasic injections at computed tomographic (CT) angiography. … Expand
