BACKGROUND The purpose of this study was to evaluate the clinical outcomes of transfusion-associated iron overload in patients with chronic refractory anemia. METHODS Clinical manifestations, main organ function, results of computed tomography (CT), endocrine evaluation, and serum ferritin levels were analyzed retrospectively in 13 patients who were transfusion-dependent for more than 1 year ...

OBJECTIVE The spot sign is related with the risk of hematoma expansion in spontaneous intracerebral hemorrhage (ICH). However, not all spot sign positive patients undergo hematoma expansion. Thus, the present study investigates the specific factors enhancing the spot sign positivity in predicting hematoma expansion. METHODS We retrospectively studied 316 consecutive patients who presented bet...

The study shows that multiaxial deformation (MAD) treatment leads to grain refinement in magnesium alloy WE43. Compared the initial state, MAD-processed exhibited smoother biocorrosion dynamics a fetal bovine serum and complete cell growth medium. Examination by microCT demonstrated retardation of decline volume Hounsfield unit values. An attendant reduction rate accumulation biodegradation pro...

Heterogeneity is a key feature of stone density as Hounsfield Unit (HU) on computer tomography (CT) for extracorporeal shock-wave lithotripsy (ESWL) outcomes predicting in urinary calculi patients. The goal this study to develop the modified 2D and 3D automate heterogeneity index variation coefficient estimation program predict ESWL treatment. For 2D, proposed was selected largest slice whole i...

BACKGROUND The purpose of this study was to identify whether the distribution of Hounsfield Unit (HU) values across the intracranial area in computed tomography (CT) images can be used as an effective diagnostic tool for determining the severity of cerebral edema in pediatric traumatic brain injury (TBI) patients. METHODS CT images, medical records and radiology reports on 70 pediatric patien...

PURPOSE The purpose of this paper is to present a new method for representing heterogeneous materials using nested STL shells, based, in particular, on the density distributions of human bones. DESIGN/METHODOLOGY/APPROACH Nested STL shells, called Matryoshka models, are described, based on their namesake Russian nesting dolls. In this approach, polygonal models, such as STL shells, are "stack...

The purpose of the study was to investigate the dosimetric effect defining the body structure with various Hounsfield unit (HU) threshold values on the dose distributions of volumetric-modulated arc therapy (VMAT) plans. Twenty patients with prostate cancer and twenty patients with head and neck (H&N) cancer were retrospectively selected. For each patient, the body structure was redefined with ...
