Multiparametric MRI-based radiomics combined with pathomics features for prediction of the efficacy of neoadjuvant chemotherapy in breast cancer

Heliyon
Purpose: The aim of this study is to investigate a new method that combines radiological and pathological breast cancer information to predict discrepancies in pathological responses for individualized treatment planning. We used baseline multiparametric

Multiparametric magnetic resonance imaging: Overview of the technique, clinical applications in prostate biopsy and future directions

Urology Research and Practice, 2019
Multiparametric magnetic resonance imaging (mpMRI) has managed to change the paradigms on prostate cancer detection and risk classification. The most clear-cut indication of mpMRI in guidelines is the patients with a history of negative biopsy/increasing

A two‐stage model for precise identification and Gleason grading of clinically significant prostate cancer: a hybrid approach

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 93-105, March 2025.
This study developed a two‐stage model using radiomics‐based multiparametric MRI and clinical indicators to help identify and grade clinically significant prostate cancer. The model showed promising levels of diagnostic accuracy and predictive performance.

Imaging of the scrotum: beyond sonography

Insights into Imaging, 2018
The aim of this article is to describe the role of second-level imaging techniques after an initial ultrasonography evaluation in the assessment of scrotal diseases. While ultrasonography remains central as the primary imaging modality for the evaluation

Retrohepatic Vena Cava Encirclement, as Surrogate of Extensive Liver Manipulation During Caval Sparing Hepatectomy, Is a Risk Factor for Tumor Recurrence After Liver Transplantation for Hepatocellular Carcinoma

Journal of Surgical Oncology, EarlyView.
ABSTRACT Introduction In liver transplantation (LT) with a caval sparing (CS) approach, the presence of complete encirclement of inferior vena cava (IVC‐E) by hypertrophic segment 1 increases the technical complexity of hepatectomy. Thus, in LT for hepatocellular carcinoma (HCC), It may be suspected that the resulting greater liver manipulation and ...

Incomplete Spoiling Correction for 3D T1$$ {T}_1 $$ Mapping

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Assess the impact of incomplete spoiling and spatial saturation on T1$$ {T}_1 $$ mapping using the variable flip angle (VFA) spoiled gradient recalled echo sequence (SPGR). Develop a correction for incomplete spoiling that results in an accurate estimate of T1$$ {T}_1 $$, essential for quantitative MRI applications.

Imaging of Central Nervous System Tumors

Acta Medica Alanya, 2018
Many Central Nerve System (CNS) tumors and even non–tumoral lesions may show a very similar imaging appearance; therefore, routine Magnetic Resonance Imaging (MRI) are lack of specificity to differentiate these lesions. The key points in the differential

The Impact of Water Exchange on Estimates of Myocardial Blood Flow and Extracellular Volume Fraction Using Dynamic Contrast‐Enhanced MRI in Patients Treated for Severe Aortic Stenosis

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To investigate the impact of intra/extracellular water exchange (WX) on quantitative dynamic contrast‐enhanced (DCE) MRI in patients with severe aortic stenosis (AS). The aims were to compare low‐dose (WX insensitive) and high‐dose (WX sensitive) DCE‐MRI measurements, and to compare data acquired before and after aortic valve ...

Functional and Structural Magnetic Resonance Imaging of Humans and Macaques [PDF]

, 2004
Magnetic resonance imaging (MRI) is a technique which finds use in the neurosciences both as an anatomical and functional localization tool. The traditional uses of MRI for structural analysis, such as are commonly found in medicine, can be adapted to ...
