Research progress on the use of the optical coherence tomography system for the diagnosis and treatment of central nervous system tumors

Ibrain, Volume 11, Issue 1, Page 3-18, Spring 2025.
With the advantages of high‐resolution imaging, efficient image acquisition, intraoperative real‐time detection, and radiation‐free and noninvasive characteristics, optical coherence tomography (OCT) provides accurate diagnosis and effective intraoperative guidance for the minimally invasive diagnosis and treatment of central nervous system (CNS ...

Computed tomography angiography: Principles and clinical applications

, 2003
Clinical applications of computed tomography (CT) angiography have increased with the improved technology of multidetector CT systems. Adequate contrast enhancement and the timing of image acquisition are key elements in producing technically adequate CT

Assessment of vitamin D levels in correlation with coronary computed tomography angiography results in a Slovak population

Introduction The growing interest in vitamin D deficiency as a potential contributor to coronary artery disease (CAD) has prompted increased scrutiny. Nevertheless, its status as a confirmed risk factor remains unestablished.

Computed tomography perfusion and computed tomography angiography in vasospasm after subarachnoid hemorrhage

, 2018
BACKGROUND: The aim of the study was to evaluate the effectiveness and reliability of a combined computed tomography angiography (CTA) and computed tomography perfusion (CTP) approach in the diagnosis of cerebral vasospasm after subarachnoid hemorrhage.

Study of Risk Factors and Image Findings of Isolated Abdominal Incidentally Detected Aortic Dissection

Journal of Clinical Ultrasound, Volume 53, Issue 3, Page 429-435, March/April 2025.
We detect the risk factors and image characteristics of incidentally detected IAAD. Independent risk factors of IAAD included fatty liver and smoking. In the ultrasound findings of IAAD, an intimal flap was frequently observed. In the CT scan, displacement of intimal calcifications was frequently observed. For suspected IAAD, the abdominal aorta should

Transcranial Color‐Coded Duplex Sonography in Large‐Vessel Vasculitis Compatible With Takayasu Arteritis Presenting Intracranial Involvement and Vertebrobasilar Dolichoectasia: A Case Report

Journal of Clinical Ultrasound, EarlyView.
This case illustrates sequential intracranial occlusions in large‐vessel vasculitis compatible with Takayasu arteritis preserving perfusion through robust collateral pathways. Transcranial color‐coded duplex sonography identified characteristic blunted flow patterns and focal turbulence, underscoring its value in detecting hemodynamic compromise beyond

Diagnostic accuracy in coronary stenosis: comparison between visual score and quantitative analysis (quantitative computed tomographic angiography) in coronary angiography by multidetector computed tomography-coronary angiography and quantitative analysis (quantitative coronary angiography) in conventional coronary angiography

, 2010
BACKGROUND: Multidetector computed tomography-coronary angiography allows quantification of coronary stenosis with a high level of accuracy; however, the inherent inaccuracy of visual score still remains.

Sonographic Diagnosis of an Intercostal Artery Pseudoaneurysm: A Case Report and Literature Review

Journal of Clinical Ultrasound, EarlyView.
A 63‐year‐old male presented to the emergency department after being found unconscious during a welfare check. Following a prolonged three‐month hospital admission, the patient developed left flank pain. Spectral Doppler ultrasound revealed a large isoechoic lesion with layering echoes, and spectral Doppler demonstrated bidirectional flow.
