With rapid advancements in imaging technology, cardiac computed tomography (CT) and magnetic resonance (MR) are increasingly being used for anatomic evaluation, functional assessment, pathologic diagnosis of the pulmonary valve right ventricle. MR is especially helpful evaluating postoperative function grading regurgitation. On other hand, CT has advantage high-resolution isovolumetric whole-chest coverage able to depict detail valve, perivalvular structures, artery branches.
To retrospectively evaluate the depiction of anatomic characteristics arterial supply to sinuatrial node (SAN) and atrioventricular (AVN) with 64-section computed tomography (CT).The institutional review board approved this HIPAA-compliant study; informed consent was not required. Anatomic origin, number, course, variants arteries SAN AVN were examined coronary multidetector CT in 102 patients (55 men, 47 women; mean age, 57 years +/- 13 [standard deviation]). Known accessory blood supplies...
Objective: This study aimed to perform comparisons between diffusion-weighted imaging (DWI) sequences at 3 T with 1.5 T. Methods: Thirteen healthy volunteers underwent abdominal DWI on both 3- and 1.5-T magnets using including breath hold without parallel (PI), PI, free breathing PI b50 b1000. Artifacts subjective image quality scores, signal intensity, apparent diffusion coefficient were compared. Results: For higher artifact was noted compared (P < 0.0001). b1000 artifacts not different...
Percutaneous left atrial appendage (LAA) closure represents a complementary option and effective treatment for patients at risk of thromboembolism, especially in whom it may be difficult to achieve satisfactory anticoagulation control or where is not possible desirable. Effective safe transcatheter LAA occlusion requires detailed knowledge crucial anatomic landmarks endocardial morphologic variants the its neighbouring structures.1 ,2 w1–w3 Our aim this article provide basic information...
With ongoing technical advances in magnetic resonance (MR) imaging, the clinical demand for cardiac MR evaluations has been increasing. Cardiac imaging techniques have evolved from traditional spin-echo sequences to breath-hold spoiled gradient-echo and balanced steady-state free precession sequences. The most recently developed allow evaluation of myocardial function, perfusion, viability; coronary angiography; flow quantification; standard morphologic assessments. However, even with...
To investigate the feasibility of 64-section multidetector computed tomography (CT) by using CT angiography (a) to demonstrate anatomic detail interatrial septum pertinent patent foramen ovale (PFO), and (b) visually detect left-to-right PFO shunts compare these findings in patients who also underwent transesophageal echocardiography (TEE).In this institutional review board-approved HIPAA-compliant study, electrocardiographically gated coronary angiograms 264 (159 men, 105 women; mean age,...
To retrospectively evaluate the anatomic characteristics of right atrial cavotricuspid isthmus (CTI) by using 64-section multi-detector row computed tomography (CT).Institutional review board approval and waiver informed consent were obtained for this HIPAA-compliant study. The region CTI was evaluated in 201 patients (116 men 85 women; mean age, 58 years +/- 11 [standard deviation]) who underwent coronary CT. length assessed along three parallel isthmic levels (paraseptal, central,...
ABSTRACT Nowadays, consent to use donor bodies for medical education and research is obtained from the body donors their families before donation. Recently, International Federation of Associations Anatomists (IFAA) published guidelines that could restrict appearance cadaveric images in commercial anatomical resources such as textbooks other educational products. These state must expressly using this purpose. Cadaveric photos drawings made dissections cadavers have been used anatomy atlases...
To retrospectively investigate anatomy of Bachmann Bundle (BB) and its vascular supply at 64-section multidetector computed tomography (CT) in healthy patients with abnormalities.The institutional review board approved this HIPAA-compliant study waived informed consent. Clinical histories, electrocardiograms (ECGs), coronary CT angiograms 317 were reviewed (healthy group, 164; group abnormalities, 153). Among 68 had atrial fibrillation (AF) or interatrial conduction block (IAB) (P wave...
Eagle syndrome refers to a clinical caused by the abnormal elongation of styloid process with calcification/ossification stylohyoid ligament. We present first reported case resulting in an external carotid artery (ECA) pseudoaneurysm. A patient presented emergency room expanding, painful right-neck mass. CT angiography three-dimensional volume rendering showed bilobed 4.0-cm right ECA pseudoaneurysm and bilateral ossification ligaments sharpened edge at level artery. Aneurysmectomy was...
