Changes in global arterial function and blood pressure pulsatility play an important role in the exponential increase in the incidence of various common afflictions of aging. However, our current approach to hemodynamics, evaluating the peak (systolic blood pressure) and trough (diastolic blood pressure) of the blood pressure waveform in the arm, provides a limited view of pulsatile hemodynamic...

Osteometric measurements of the femur are consistently used to estimate stature, sex, and race in constructing demographic profiles. The presence of positive or negative changes in the size of the maximum vertical diameter of the femoral head could potentially affect the validity of such profiles. Additionally, changes in femoral head size may be an indicator of the socioeconomic status, health...

background: one of the main problems of dedicated iort accelerators is to determine dosimetric characteristics of the electron beams. monte carlo simulation of iort accelerator head and produced beam will be useful to improve the accuracy of beam dosimetry. materials and methods: liac accelerator head was modeled using the beamnrcmonte carlo simulation system. phase-space files were generated a...

BACKGROUND The purpose of this study was to assess the influence of head and neck pathologies on the detection rate, configuration and diameter of the thoracic duct (TD) and right lymphatic duct (RLD) in computed tomography (CT) of the head and neck. METHODS One hundred ninety-seven patients were divided into the subgroups "healthy", "benign disease" and "malignant disease". The interpretatio...

Hip joints (280) from 140 human fetuses, obtained from abortions and deaths in the perinatal period, were studied. The fetuses ranged from 8.7 to 40 cm in crown-rump length and are believed to be between 12 and 42 weeks in age. The joints were dissected, morphology inspected, and measurements taken of the depth and diameter of the acetabulum, the diameter of the femoral head, length and width o...

Objective: The aim of this study was to compare the fetal biometric growth measurements (Head Circumference, Bi-Parietal Diameter, and Femur Length) between male female fetuses on antenatal ultrasound in our population. Methodology: This an observational carried out Department Radiology CMH Malir, Karachi Ziauddin hospital, from July 2016 till 2018 using non-probability sampling technique. A to...

Introduction: Quality assurance in Computed tomography (CT) centers in developing countries are largely hindered by the unavailability of CT phantoms. The development of a local CT phantom for the measurement of organ radiation absorbed dose is therefore requisite. Material and Methods: Local CT phantoms were designed to meet the standard criteria of 32 cm diameter for body, 16 cm diameter for...
