Endoscopic Proximal Adductor Lengthening For Chronic Adductor-Related Groin Pain, S. Bharam, P. V. Bhagat, M. C. Spira, D. A. Klein

Journal Articles

© 2018 Arthroscopy Association of North America Proximal adductor injuries are relatively common groin injuries in athletes. Various tenotomy techniques have been described including open, partial, and percutaneous approaches. Current techniques help most athletes return to sport; however, many develop adductor weakness. Moreover, the procedures lack full visualization of the tendon and do not allow for return to athletes’ preinjury level of play. We describe an endoscopic z-lengthening of the proximal adductor tendon with the potential to minimize complications associated with open procedures such as incisional pain and neurovascular injury while affording a more complete tenotomy than current percutaneous techniques. This ...

Journal Articles

© Cardiovascular Diagnosis and Therapy. All rights reserved. Pulmonary embolism (PE) is a leading cause of morbidity and mortality worldwide. PE is a complex disease with a highly variable presentation and the available treatment options for PE are expanding rapidly. Anticoagulation (AC), systemic lysis, surgery, and catheter-directed thrombolysis (CDT) play important roles in treating patients with PE. Thus, a multidisciplinary approach to diagnosis, risk stratification, and therapy is required to determine which treatment option is best for a given patient with this complex disease.

Congenital Rhabdomyosarcoma Presenting As A Neck Mass At Birth., L. E. Waldman, A. K. Williamson, J. B. Amodio, L. Collins

Journal Articles

Rhabdomyosarcoma is a malignant tumor of the soft tissues which preferentially affects the pediatric population. Neonatal rhabdomyosarcoma is rare, and much of the published literature concerning this entity consists of isolated case reports and small case series. Recent work involving the classification of rhabdomyosarcoma has helped to delineate prognostic information based on gene rearrangements. Here, we present a case of congenital rhabdomyosarcoma seen in utero which manifested as a neck mass at birth and was found to harbor a favorable gene fusion.

Interpreting 123i-Ioflupane Dopamine Transporter Scans Using Hybrid Scores., K. J. Nichols, B. Chen, M. B. Tomas, C. J. Palestro

Journal Articles

Dopamine transporter (DaT) 123I-FP-CIT scans most commonly are interpreted visually. Alternatively, absolute quantitation of radiopharmaceutical uptake may improve scan accuracy. However, neither approach accomodates dependence of striatal uptake on age and gender. We investigated whether demographic indexing of visual and numerical variables improve discrimination of patients with essential tremor (ET), Parkinson's disease (PD), and dementia with Lewy bodies (DLB).Data of 132 consecutive patients undergoing DaT SPECT scans were reviewed retrospectively. The clinical impression in the latest neurology note was utilized as the final clinical diagnosis. Caudate and putamen specific binding ratio (PSBR) were computed. 123I calibration phantoms were ...

Radioresistance Of Brain Tumors, K. Kelley, J. Knisely, M. Symons, R. Ruggieri Jan 2016

Radioresistance Of Brain Tumors, K. Kelley, J. Knisely, M. Symons, R. Ruggieri

Journal Articles

Radiation therapy (RT) is frequently used as part of the standard of care treatment of the majority of brain tumors. The efficacy of RT is limited by radioresistance and by normal tissue radiation tolerance. This is highlighted in pediatric brain tumors where the use of radiation is limited by the excessive toxicity to the developing brain. For these reasons, radiosensitization of tumor cells would be beneficial. In this review, we focus on radioresistance mechanisms intrinsic to tumor cells. We also evaluate existing approaches to induce radiosensitization and explore future avenues of investigation.

Journal Articles

Deformable image registration (DIR) and interobserver variation inevitably intro-duce uncertainty into the treatment planning process. The purpose of the current work was to measure deformable image registration (DIR) errors and interobserver variability for regions of interest (ROIs) in the head and neck and pelvic regions. Measured uncertainties were combined to examine planning margin adequacy for contours propagated for adaptive therapy and to assess the trade-off of DIR and interobserver uncertainty in atlas-based automatic segmentation. Two experi-enced dosimetrists retrospectively contoured brainstem, spinal cord, anterior oral cavity, larynx, right and left parotids, optic nerves, and eyes on the planning CT (CT1) and ...

Journal Articles

BACKGROUND AND PURPOSE: Global cerebral edema is an independent predictor of mortality and poor outcomes after aneurysmal SAH. Global cerebral edema, a complex disease process, is thought to be associated with an altered cerebral autoregulatory response. We studied the association between cerebral hemodynamics and early global cerebral edema by using CTP. MATERIALS AND METHODS: We retrospectively studied consecutive patients with aneurysmal SAH with admission CTP performed at days 0-3. Two neuroradiologists classified global cerebral edema and hydrocephalus on NCCT performed concurrently with CTP. Global cerebral edema was defined as diffuse effacement of the sulci and/or basal cisterns or diffuse ...

Robust Low-Dose Ct Perfusion Deconvolution Via Tensor Total-Variation Regularization, R. G. Fang, S. T. Zhang, T. H. Chen, P. C. Sanelli

Journal Articles

Acute brain diseases such as acute strokes and transit ischemic attacks are the leading causes of mortality and morbidity worldwide, responsible for 9% of total death every year. "Time is brain" is a widely accepted concept in acute cerebrovascular disease treatment. Efficient and accurate computational framework for hemodynamic parameters estimation can save critical time for thrombolytic therapy. Meanwhile the high level of accumulated radiation dosage due to continuous image acquisition in CT perfusion (CTP) raised concerns on patient safety and public health. However, low-radiation leads to increased noise and artifacts which require more sophisticated and time-consuming algorithms for robust estimation ...

Journal Articles

BACKGROUND: Carotid plaque MRI has been a useful method to characterize vulnerable atherosclerotic plaque elements. Recent investigations have suggested that source images from CT angiography (CTA) and MR angiography (MRA) can identify the simple high-risk features of symptom-producing carotid artery plaque. We studied the correlation and relative diagnostic accuracies of CTA and MRA source images in detecting symptomatic carotid artery plaque. METHODS: Subjects were eligible if they had carotid stenosis between 50 and 99% and had MRA and CTA exams performed within 10 days of one another. We measured the soft (non-calcified) plaque and hard (calcified) plaque thickness on CTA ...


Effect Of Reconstruction Algorithms On The Accuracy Of (99m)Tc Sestamibi Spect/Ct Parathyroid Imaging, K. J. Nichols, G. G. Tronco, C. J. Palestro Jan 2015

Effect Of Reconstruction Algorithms On The Accuracy Of (99m)Tc Sestamibi Spect/Ct Parathyroid Imaging, K. J. Nichols, G. G. Tronco, C. J. Palestro

Journal Articles

The superiority of SPECT/CT over SPECT for (99m)Tc-sestamibi parathyroid imaging often is assumed to be due to improved lesion localization provided by the anatomic component (computed tomography) of the examination. It also is possible that this superiority may be related to the algorithms used for SPECT data reconstruction. The objective of this investigation was to determine the effect of SPECT reconstruction algorithms on the accuracy of MIBI SPECT/CT parathyroid imaging. We retrospectively analyzed preoperative MIBI SPECT/CT parathyroid imaging studies performed on 106 patients. SPECT data were reconstructed by filtered back projection (FBP) and by iterative reconstruction ...

Radionuclide Imaging: Past, Present And Future Outlook In The Diagnosis Of Infected Prosthetic Joints, L. Brammen, C. Palestro, H. Sinzinger

Journal Articles

Objective: A serious complication of joint replacement surgery is infection, which results in prolonged invalidity as well as removal and subsequent re-implantation after lengthy antibiotic therapy. In terms of diagnostic imaging, nuclear medicine has presented several tracers and imaging modalities over the years to be used in prosthetic joint infection. The PubMed/MEDLINE literature database was systematically examined for publications on infection, arthroplasty, joint replacement, prosthetic joint, gallium, labeled leukocytes, sulfur colloid, antimicrobial peptides, Fluorine-18-fluorodeoxyglucose (F-18-FDG), positron emission tomography/computed tomography (PET-CT), and single-photon emission (SPET-CT). This was determined to be a comprehensive review, not a meta-analysis of prosthetic joint ...
