Abstract Purpose: To evaluate the reproducibility and gender differences in cerebrovascular reactivity (CVR) measurements obtained using blood‐oxygen level dependent (BOLD) response to controlled changes end‐tidal partial pressure of carbon dioxide (P ET CO 2 ). Materials Methods: We ethical approval image 19 healthy volunteers (10 men, 9 women) on a 1.5 Tesla (T) MRI scanner twice two separate days identical procedures. CVR images were generated by collecting BOLD data during P induced...
Abstract The purpose of this guideline is to provide a list critical performance tests assist the Qualified Medical Physicist (QMP) in establishing and maintaining safe effective quality assurance (QA) program. on linear accelerator (linac) should be selected fit clinical patterns use care given perform which are relevant detecting errors related specific accelerator. Current recommendations for linac QA were reviewed determine any changes required those highlighted by original report as...
Abstract Purpose: To provide the first comparison of absolute renal perfusion obtained by arterial spin labeling (ASL) and separable compartment modeling dynamic contrast‐enhanced (DCE) magnetic resonance imaging (MRI). Moreover, we application dual bolus approach to quantitative DCE‐MRI measurements in kidney. Materials Methods: Consecutive ASL acquisitions were performed on six rabbits a 1.5 T MRI system. Gadolinium (Gd)‐DTPA was administered two separate injections decouple measurement...
At our institution, we have historically treated brain metastasis (BM) ≤2 cm in eloquent with a radiosurgery (SRS) lower prescription dose (PD) to reduce the risk of radionecrosis (RN). We sought evaluate impact this practice on outcomes.We analyzed prospective registry BM patients SRS between 2008 and 2017. Incidences local failure (LF) RN were determined Cox regression was performed for univariate multivariate analyses (MVAs).We evaluated 1533 cm. Median radiographic follow-up post 12.7...
OBJECTIVES: To discover postoperative symptom differences between nerve-sparing and nerve-sacrificing techniques during ORIF of clavicle fractures. METHODS: Design : Prospective, partially blinded randomized controlled trial Setting: Single academic Level I Trauma Center Patient Selection Criteria: Patients with closed, isolated, displaced, midshaft fractures (OTA/AO 15-2A, -2B, -2C) underwent were consented to a “nerve-sacrificing” or “nerve-sparing” group. Outcome Measures Comparisons:...
To develop a practice-based training strategy to transition from radiation oncologist therapist-driven prostate MR-Linac adaptive radiotherapy.In phase 1, 7 therapists independently contoured the and organs-at-risk on T2-weighted MR images 11 previously treated patients. Contours were evaluated quantitatively (i.e. Dice similarity coefficient [DSC] calculated against generated online contours) qualitatively using 5-point Likert scale; score ≥ 4 was deemed pass, 90% pass rate required proceed...
Magnetic resonance imaging (MRI) relaxation times provide indirect estimates of tissue O(2) for monitoring tumour oxygenation. This study provides insight into mechanisms underlying longitudinal (R(1) = 1/T(1)) and transverse effective (R(2)* 1/T(2)*) rate changes during inhalation 100% 3%, 6% 9% CO(2) (balanced O(2)) in a rabbit model. Quantitative R(1), R(2)*, dynamic contrast-enhanced (DCE) was performed six rabbits 12-23 days following implantation VX2 carcinoma cells the quadricep...
