Effectiveness of Contrast-Enhanced Spectral Mammography Following Contrast-Enhanced Computed Tomography in Breast Cancer Diagnosis [PDF]

Diagnostics
Background: Contrast-enhanced spectral mammography (CEM) provides functional information on tumor vascularity and is increasingly used for breast imaging, particularly as an alternative to breast MRI in selected clinical scenarios.

The prevalence of undiagnosed abnormalities on non-contrast-enhanced computed tomography compared to contrast-enhanced computed tomography of the brain

South African Journal of Radiology, 2014
Background: Even though magnetic resonance imaging (MRI) is the gold standard investigation for intracranial pathology, it is not widely available in developing countries and computed tomography (CT) of the brain remains the first-line investigation for ...

Dynamic contrast‐enhanced computed tomography in dogs with nasal tumors

Journal of Veterinary Internal Medicine, 2023
Background Treatment of nasal tumors in dogs is associated with high morbidity and reliable prognostic factors are lacking. Dynamic contrast‐enhanced computed tomography (DCECT) can be used to assess tumor perfusion.

Enhanced Visualization: Transforming Non-Contrast into Contrast-Enhanced Computed Tomography Images Through Advanced Generative Adversarial Networks [PDF]

Diagnostics
Background/Objectives: Contrast-enhanced CT (CECT) is essential for mediastinal and lymph node assessment but is often limited in patients with renal dysfunction, prior severe contrast reactions, or pediatric populations.

Assessment of Abdominal Aorta Diameter on Contrast-enhanced Computed Tomography: A MDCT-based Observational Study [PDF]

Journal of Clinical and Diagnostic Research, 2023
Introduction: Average size of the abdominal aorta is less than 3 cm which variates with time. The increase in abdominal aortic dimensions more than 3 cm can result in the presence of ectasia which can further convert into an aneurysm.

Clival Chordoma in an Indian Female Patient: A Case Report [PDF]

International Journal of Anatomy Radiology and Surgery, 2021
Chordomas are rare tumours that originate anywhere along the craniospinal axis and present various diagnostic hurdles. High recurrence rate even after treatment and tendency to involve other regions within the craniospinal axis make this condition more

Untargeted Contrast-Enhanced Ultrasound Versus Contrast-Enhanced Computed Tomography: A Differential Diagnostic Performance (DDP) Study for Kidney Lesions [PDF]

Clinics, 2020
OBJECTIVES: Histopathology is the ‘gold standard’ for diagnosing renal cell carcinoma but is limited by sample size. Contrast-enhanced ultrasound can differentiate malignant and benign lesions, but the Chinese guidelines on the management of renal cell ...

Contrast enhanced computed tomography of small ruminants: Caprine and ovine.

PLoS ONE, 2023
The use of small ruminants, mainly sheep and goats, is increasing in biomedical research. Small ruminants are a desirable animal model due to their human-like anatomy and physiology.

Case Report: The value of contrast-enhanced ultrasound and contrast-enhanced computed tomography in the diagnosis of hepatic angiosarcoma

Frontiers in Oncology, 2023
BackgroundEnhanced imaging techniques have the overwhelming advantages of being noninvasive and sensitive enough to evaluate the microcirculation of lesions, thus making them accurate in the diagnosis of hepatic lesions.

Multimodality CT imaging contributes to improving the diagnostic accuracy of solitary pulmonary nodules: a multi-institutional and prospective study

Radiology and Oncology, 2023
Solitary pulmonary nodules (SPNs) are one of the most common chest computed tomography (CT) abnormalities clinically. We aimed to investigate the value of non-contrast enhanced CT (NECT), contrast enhanced CT (CECT), CT perfusion imaging (CTPI), and dual-
