Accurate assessment of locoregional response to neoadjuvant chemotherapy (NAC) is important for surgical planning, particularly in regard to management of the axilla. We evaluated the correlation between radiologic complete response (rCR) in the axilla on magnetic resonance imaging (MRI) and the likelihood of pathologic complete response (pCR) at the time of breast cancer surgery following NAC. Our institutional database was queried for patients who underwent NAC from 2010-2016 and had a preand ...
Study on the Variations of Image Density Index of MDCT for Healthy Lungs

We selected several image density indices to establish CAD for prediction of biopsy in lung diseases. Our results suggested that significant difference was not observed in the image density indices between bilateral lungs at each slice level. Our own designed image indices may be reliable parameters in the establishment of CAD system and pathologic diagnosis for lung disease. There has been a rapid progress in the modality of CT since it was developed by Mr. Hounsfield. The earlier CT had been u...
Long Segment Aplasia of the Great Saphenous Vein Associated with Short Saphenous Vein Connection: A Case Report
Mohammed Alagha and Mariam Mattar
Article Type: Case Report | First Published: December 22, 2018
Localised hypoplasia or aplasia of the great saphenous vein (GSV) is not uncommon, with reports primarily describing limited area of hypoplasia/aplasia around the knee. Long segment of hypoplasia/aplasia extending along the thigh and distally to lower calf is rare. We report a case of an 81-year-old lady with long segment of the GSV aplasia depicted 3 cm distal to sapheno-femoral junction (SFJ), down to 5 cm above the right ankle with direct communication with the short saphenous vein (SSV)....

Meningiomas are the most common intracranial benign tumors. While an indolent natural history is typical for benign meningiomas, a wide spectrum of symptoms may occur depending on lesion location and proximity to critical neurovascular structures. A multidisciplinary approach may be warranted for optimal management of meningiomas. In the scarcity of prospective, randomized controlled studies to dictate treatment algorithms, decision making for treatment is based primarily on mostly retrospective...
Tensor Voting Based Vascular Bifurcation Detection in CT Images of Lung
Ruifang Sun, Jingli Shi and Xuan Yang
Article Type: Research Article | First Published: November 08, 2018
The accurate detection of vascular bifurcations is not helpful for pulmonary vascular disease diagnosis, but vital in (Computed Tomography) CT image analysis and processing of lung. We propose a tensor voting based method for vascular bifurcation detection in CT image of lung, which a vessel enhancement method is firstly proceeding to initially extract vessel structure, on which we perform ball voting with the pixels. Then counting the number of votes of each pixel and calculating the local maxi...

This study was aimed that the evaluation of tissue elasticity for determination of the characterization of bladder masses. The prospective study was performed between May and September 2014. This study included 39 patients who presented with microscopic or gross hematuria and had primary bladder mass and according to ultrasound or computed tomography results. ARFI elastography was performed by one experienced radiologist then, the shear wave velocity was measured. Two measurements were performed...
The Role of the Diffusion Tensor Imaging and the MR Tractography in the Evaluation of the Ischemic Cerebral Strokes

Article Type: Research Article | First Published: October 12, 2018
Cerebral stroke is a worldwide concern, it's classified as the most second cause of death in 2008. In this year 5.7 million deaths and about nine million patients had cerebral strokes events with resultant variable degrees of disabilities. The primary goal in stroke management is to reach an early accurate diagnosis for the patients, which will affect the choice of the treatment lines among the newly developed programs and the end stage recovery. The DTI & DTT are MRI techniques used for the 3D ...
More Than Meets the Eye: Inattentional Blindness
Ann-Christin Sannes, Aleksander Chaibi and Peter W McCarthy
Article Type: Research Article | First Published: October 06, 2018
The phenomenon of inattentional blindness has been discussed for years, in relation to everyday life and clinical practice. Inattentional blindness refers to the common failure to notice plainly visible items when attention is otherwise preoccupied. The purpose of this study was to assess any potential difference in inattentional blindness between chiropractic students on assessing plain film radiograph, and any difference compared to expert radiologist....
