Abstract Anti-BRAF/EGFR therapy was recently approved for the treatment of metastatic BRAF V600E colorectal cancer (mCRC BRAF-V600E ). However, a large fraction patients do not respond, underscoring need to identify molecular determinants response. Using whole-exome sequencing in discovery cohort with mCRC treated anti-BRAF/EGFR therapy, we found that inactivating mutations RNF43 , negative regulator WNT, predict improved response rates and survival outcomes microsatellite-stable (MSS)...
The aim of this work has been to determine typical occupational dose levels in interventional radiology and cardiology installations relate doses patient dosimetry through the dose-area product. An experimental correlation between environmental dosimetric records products centres studied was established. study covered a sample 83 procedures performed by 10 specialists six laboratories. radiologists cardiologists monitored wore nine thermoluminescent chips next eyes, forehead, neck, hands,...
To report estimated radiation doses to the eye lens of interventionalist from procedures performed with and without use protection measures.Scattered for seven interventional radiology fluoroscopic systems were measured by using phantoms simulating patients 16-28 cm in thickness undergoing low-, medium-, high-mode fluoroscopy, cine cardiac imaging, digital subtraction angiography (DSA). The low- high-dose scenarios estimated. Beam angulation, biplanar equipment, working distance, procedure...
This report describes occupational radiation doses of interventional cardiologists over 15 years and assesses action undertaken to optimize protection. Personal dosimetry records nine staff eight cardiology fellows were recorded using personal dosemeters worn under their lead aprons. The hospital in which this study was conducted currently performs 5000 procedures per year. has improved its facilities since 1989, when it had two old-fashioned theatres, include four rooms with more advanced...
Abstract Large exposures incurred in interventional radiology procedures make it advisable to establish reference dose values. These values should be quoted quantities representative of the radiological risk patient. In Spain, measurement methods were developed comply with European Directive on Patient Protection. Dose-area product and, when feasible, surface using thermoluminescent dosimetry chips measured. Both approaches are discussed, as well their potential use patient protection...
Coronary angiography and percutaneous transluminal coronary angioplasty procedures performed in four different facilities were monitored the present study by measuring maximum skin dose, dose-area product other operational parameters. Radiographic slow film, thermoluminescent dosemeters transmission ion chambers used to measure dose related quantities. Values of 107-711 mGy for 27.3-370.6 Gy cm2 found, together with cumulative estimates 110-3706 mGy. A discussion relationship measured values...
Context. The ESO public survey VISTA Variables in the Vía Láctea (VVV) surveyed inner Galactic bulge and adjacent southern disk from 2009–2015. Upon its conclusion, complementary VVV extended (VVVX) has expanded both temporal as well spatial coverage of original area, widening it 562 to 1700 sq. deg., providing additional epochs JHK s filters 2016–2023. Aims. With completion VVVX observations during first semester 2023, we present here observing strategy, a description data quality access,...
Patient and staff dose values in an interventional cardiology laboratory for different operational modes several patient thicknesses (from 16 to 28 cm, simulated using polymethylmethacrylate) are presented. When increasing depending on fluoroscopy cine modes, occupational doses can increase >30 times the baseline level. Scatter rates at cardiologist's position with no radiation protective tools ranged from 1 14 mSv h−1 fluoroscopy, 10 47 during acquisition. entrance surface air kerma...

In the present investigation, we analyze dose of 5034 patients (20 137 images) who underwent mammographic examinations with a full‐field digital mammography system. Also, evaluate system calibration by analyzing exposure factors as function breast thickness. The information relevant to this study has been extracted from image DICOM header and stored in database during 3‐year period (March 2001–October 2003). Patient data included age, thickness, kVp, mAs, target/filter combination, nominal...
To retrospectively evaluate patient radiation doses in projection radiography after the transition to computed (CR) authors' hospital.The hospital's ethical committee approved study and waived informed consent. In 2001, a dose reduction initiative was implemented, which involved collecting radiographic parameters, calculating entrance doses, monitoring changes with an online computer, training program for radiographers conducted. A database 204 660 values used compute over time. Sample sizes...
<h3>BACKGROUND AND PURPOSE:</h3> Radiation exposure from neurointerventional procedures can be substantial, with risk of radiation injuries. We present the results a follow-up program applied to potential skin injuries in interventional neuroradiology based on North American and European guidelines. <h3>MATERIALS METHODS:</h3> The following guidelines approved 2009 by SIR CIRSE have been used over last 2 years identify patients requiring clinical follow-up: peak dose >3 Gy, air kerma at...

In 2011, the International Commission on Radiologic Protection established an absorbed-dose threshold to brain of 0.5 Gy as likely produce cerebrovascular disease. this paper, authors investigated doses delivered patients during clinical neuroradiology procedures in a university hospital.The radiation dose was 99 diagnostic and therapeutic interventional procedures. Brain were calculated mathematic model adult standard anthropomorphic phantom by using technical data x-ray biplane system...
The purpose of this work is to evaluate radiation doses the lens urologists during interventional procedures and compare them with values measured radiology, cardiology vascular surgery. measurements were carried out in a surgical theatre using mobile C-arm system electronic occupational dosimeters (worn over lead apron). Patient staff dose collected sample 34 urology interventions (nephrolithotomies). same dosimetry was used other medical specialties for comparison purposes. Median 3rd...
Objectives: Radiation dose management systems (DMS) are currently used to help improve radiation protection in medical imaging and interventions. This study presents our experience using a homemade DMS called DOLQA (Dose On-Line for Quality Assurance).
