Imaging Misdiagnosis Analysis of a Rare Case of Renal Subcapsular Hematoma Located in the Renal Hilum and Collecting Area

open access: yesUrology Case Reports, 2014
We report a rare case of renal subcapsular hematoma, which was located in the renal hilum and collecting area. Preoperative ultrasonography, retrograde urethrography, and computed tomographic examinations misdiagnosed the patient with simple ...

Contrast-enhanced Computed Tomography Screening Is Effective for Detecting Venous Thromboembolism not Prevented by Prophylaxis after Total Knee Arthroplasty [PDF]

open access: yes, 2015
Venous thromboembolism (VTE) is a potential complication occurring after total knee arthroplasty (TKA). We investigated the incidence of VTE after TKA using contrast-enhanced computed tomography (CT), and assessed the efficacy of VTE prophylaxis ...

Contrast-enhanced ultrasonography in hepatosplenic sarcoidosis [PDF]

open access: yes, 2011
We report a case of a 38-year-old woman with atypical pain in the left lower hemi-abdomen. On abdominal B-mode ultrasonography the liver was normal; the spleen showed multiple subcentimetric hypoechoic nodules.

Negative effects of iodine-based contrast agent on renal function in patients with moderate reduced renal function hospitalized for COVID-19

open access: yesBMC Nephrology, 2021
Background Kidney disease and renal failure are associated with hospital deaths in patients with COVID − 19. We aimed to test if contrast enhancement affects short-term renal function in hospitalized COVID − 19 patients.

Focal Lesions of the Liver and Radiomics: What Do We Know?

open access: yesDiagnostics, 2023
Despite differences in pathological analysis, focal liver lesions are not always distinguishable in contrast-enhanced magnetic resonance imaging (MRI), contrast-enhanced computed tomography (CT), and positron emission tomography (PET).

The feasibility of non-contrast enhanced plus contrast-enhanced computed tomography in discriminating invasive pure ground-glass opacity from pre-invasive pure ground-glass opacity

open access: yesJournal of Cardiothoracic Surgery, 2020
Background Invasive pure ground-glass opacity and pre-invasive pure ground-glass opacity have different 5-year overall survival rate and risk of lymph node metastasis and the extent of resection.

Early Contrast Enhancement: a novel Magnetic Resonance Imaging biomarker of pleural malignancy [PDF]

open access: yes, 2018
Introduction: Pleural Malignancy (PM) is often occult on subjective radiological assessment. We sought to define a novel, semi-objective Magnetic Resonance Imaging (MRI) biomarker of PM, targeted to increased tumour microvessel density (MVD) and ...

Activity-based cost analysis of contrast-enhanced ultrasonography (CEUS) related to the diagnostic impact in focal liver lesion characterisation [PDF]

open access: yes, 2015
Purpose This study was done to assess the clinicaldiagnostic impact and cost of contrast-enhanced ultrasound (CEUS) versus computed tomography (CT) and magnetic resonance (MR) imaging in the characterisation of focal liver lesions. Materials and methods

Texture analysis of aggressive and nonaggressive lung tumor CE CT images [PDF]

open access: yes, 2008
This paper presents the potential for fractal analysis of time sequence contrast-enhanced (CE) computed tomography (CT) images to differentiate between aggressive and nonaggressive malignant lung tumors (i.e., high and low metabolic tumors).
