Introduction In vivo MR carotid plaque imaging has been used to identify vessel morphology and plaque characteristics, and their associations with clinical symptoms. [1] Two-dimensional T1 weighted (T1W) double inversion recovery spin echo [2] and subsequently quadruple inversion recovery spin echo sequences [3] have been used to obtain the contrast between vessel wall and lumen, and identify c...

background hepatitis c virus (hcv) infection is the most significant source of chronic liver diseases in the globe. about 170 million individuals are infected by hcv worldwide. the reported prevalence of hcv in different areas of khyber pakhtunkhwa (kp) ranges from 4.1 to 36%. objectives the current study aimed to analyze the true prevalence of hcv infection in khyber pakhtunkhwa, pakistan. mat...

Recently, several fully distributed (localized) GPS based routing protocols for a Mobile Ad hoc NETwork (MANET) were reported in literature. They are variations of directional (DIR) routing methods, in which node A (the source or intermediate node) transmits a message m to several neighbors whose direction is closest to the direction of D. We also found an older, MFR (most forward progress with...

PURPOSE The aims of this work were to evaluate the performance of several deformable image registration (DIR) algorithms implemented in our in-house software (NiftyReg) and the uncertainties inherent to using different algorithms for dose warping. METHODS The authors describe a DIR based adaptive radiotherapy workflow, using CT and cone-beam CT (CBCT) imaging. The transformations that mapped ...

INTRODUCTION: The Double Inversion Recovery Fast spin echo (DIR-FSE) sequence [1] is a key component of cardiac MR examination. It allows to homogenously suppress blood signal for a better depiction of the myocardium. Black blood imaging of the heart is usually performed during the mid-diastolic rest. This is a consequence of the long inversion time (TI) required to suppress the blood signal wh...

Visceral leishmaniasis is endemic in District Dir, NWFP. We evaluated 10 patients with visceral leishmaniasis at DHQ Hospital Timergara District Dir, N.W.F.P. All patients were in the age range 2 to 10 years. The predominant clinical features in these were chronic fever (10), splenomegaly (10), hepatomegaly (10), weight loss (10) and abdominal distention (5). Lymphadenopathy was absent. Common ...

The quality of adaptive treatment planning depends on the accuracy of its underlying deformable image registration (DIR). The purpose of this study is to evaluate the performance of two DIR algorithms, B-spline-based deformable multipass (DMP) and deformable demons (Demons), implemented in a commercial software package. Evaluations were conducted using both computational and physical deformable...

W hen we talk among ourselves about our business, we use lots of abbreviations and acronyms. We take a lot of things for granted. To understand what I’m talking about all you need to do is try to explain how you get paid to somebody. AWP, WAC, discount, PBM, RA, EOB, DIR, copay, insured amount, rebate, clawback, etc. This is the barrier we face when talking to legislators. We are in a complicat...

A new world, digital image ratio (DIR), has been developed for directly measuring changes in alveolar bone. The image on the computer monitor represents the relative mass change between two radiographs. Fourier filtering is used to reduce noise artefacts. This method is validated through an experiment with a step wedge. DIR needs only a preliminary calibration of the experimental conditions of ...
