PET/CT

Evaluation Of PET/CT In Metastatic Brain Lesions

Since its introduction, positron emission tomography (PET) fused with computed tomography (CT) (PET/CT) has gained a crucial role in the everyday clinical practice of medical imaging, particularly in oncology for both solid tumors and lymphomas. 18F-fluorodeoxyglucose (18F-FDG) has long been the radiopharmaceutical of choice for the PET/CT evaluation of oncology patients. Evaluation of Intracranial Lesions…

Prognostic Map To Target Tumor Using FDG-PET/CT imaging

To construct a tumor voxel Dose Response Matrix (DRM) and Dose Prescription Function (DPF) for adaptive Dose Painting by Number (DPbN) based on treatment feedback of FDG-PET/CT imaging. The uniform prescription dose, which has been safely used in clinics, has significant limitations to destroy local resistant niches in tumors that cause radiotherapy failures. Hence the…

COPD Using SPECT/CT

Quantify Lung Neutrophil Clearance In COPD

COPD is a complex and heterogeneous condition in which neutrophils play a central role. Studying neutrophil accumulation across all lung compartments is challenging due to a lack of direct ‘whole lung’ assessment techniques. The aim of this study was to validate a new non-invasive method for measuring whole lung neutrophil accumulation in patients with stable…

99mTc-DTPA SPECT/CT In Diagnosing In Graves’ Disease

The most frequently used methods of assessing Graves’ orbitopathy (GO) include Clinical Activity Score (CAS), ultrasonography (USG), computed tomography (CT), and magnetic resonance imaging (MRI). There exists another, slightly forgotten, imaging method: single-photon emission computed tomography (SPECT) with the use of diethylenetriaminepentaacetic acid tagged with 99mTc (99mTc-DTPA). 

Implementation And Application On The Example of DCE-MRI

Many medical imaging techniques use fitting approaches for quantitative parameter estimation and analysis. Common examples are pharmacokinetic modeling in dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) / computed tomography (CT), apparent diffusion coefficient calculations and intravoxel incoherent motion modeling in diffusion-weighted MRI and Z-spectra analysis in chemical exchange saturation transfer MRI. 

CT Or MRI: Abdominal Compartment Syndrome In Children

The objective of our study was to identify the clinical features and imaging findings of the abdominal compartment syndrome (ACS) in children. During the study, ACS was diagnosed in 50 children, 14 of whom underwent CT or MRI. We reviewed the medical records of the 50 children to obtain clinical information, such as underlying risk factors, therapeutic approach, and clinical outcome, and we evaluated the CT and MRI examinations of the 14 children.
