ABSTRACT Hypopharyngeal squamous cell carcinoma (HSCC) is an aggressive subtype of head and neck squamous cell carcinoma with insidious onset, early metastasis, and dismal prognosis. Conventional multimodal therapy achieves limited survival benefit, highlighting an urgent need for refined precision strategies.

Correlation of volume transfer coefficient Ktrans with histopathologic grades of gliomas [PDF]
AbstractPurpose:To evaluate the roles of dynamic contrast‐enhanced magnetic resonance imaging (DCE‐MRI) and optimum tracer kinetic parameters in the noninvasive grading of the glial brain tumors with histopathological grades (I–IV).Materials and Methods:Twenty‐eight patients with histopathologically graded gliomas were imaged.

Blood vascular permeability is a hallmark of cancer and acts as an active driver of metastatic dissemination. Metastasis accounts for the vast majority of cancer deaths, yet most work has focussed on tumour‐intrinsic traits and angiogenesis, while the specific contribution of endothelial barrier regulation to intravasation and extravasation remains ...

Targeting KRAS for cancer therapy
In recent years, therapeutics targeted against KRAS proto‐oncogene GTPase (KRAS)‐mutant cancers have seen significant progress. Herein we outline the biology and epidemiology of KRAS alterations at the lineage and allele levels, reviewing the clinical evidence for KRASG12C inhibition from the discovery of the recessive switch pocket to sotorasib ...

ABSTRACT Purpose To determine the feasibility of measuring brain clearance of gadolinium contrast agent using standard intravenous DCE‐MRI acquisitions and evaluate the contribution of blood–brain barrier (BBB) and non‐BBB clearance routes. Methods Uptake and extended Tofts models were fit to DCE‐MRI data from people with Parkinson's disease, post ...

Evaluating differential nanoparticle accumulation and retention kinetics in a mouse model of traumatic brain injury via Ktrans mapping with MRI [PDF]
AbstractTraumatic brain injury (TBI) is a leading cause of injury-related death worldwide, yet there are no approved neuroprotective therapies that improve neurological outcome post-injury. Transient opening of the blood-brain barrier following injury provides an opportunity for passive accumulation of intravenously administered nanoparticles through ...

In Vivo Correlation of Glucose Metabolism, Cell Density and Microcirculatory Parameters in Patients with Head and Neck Cancer: Initial Results Using Simultaneous PET/MRI. [PDF]
To demonstrate the feasibility of simultaneous acquisition of 18F-FDG-PET, diffusion-weighted imaging (DWI) and T1-weighted dynamic contrast-enhanced MRI (T1w-DCE) in an integrated simultaneous PET/MRI in patients with head and neck squamous cell cancer (

Demarcation of the operating renal cortex in a coronal reformation of the Ktrans maps (A).
Cortex volume, calculated with a volume-program by setting upper and lower limits (upper limit 300 mL/100 mL/min, lower limit 80 mL/100 mL/min, volume 59 mL, mean Ktrans 98±10 (B). r2 map shows linearity of the Patlak fit in % (C).
