stronghold 3 crack chomikuj.pl Cardiologists exposed to more radiation during angiography for obese patients

cracked corn mash moonshine recipe programas para hackear cuentas de facebook 2012 Physicians were exposed to seven times the amount of radiation when they performed coronary angiography on morbidly obese patients compared to those with normal bodyweights, according to a single-center cách crack idm khi bi khoa published Jan. 2 in Circulation: Cardiovascular Interventions.

keygen pervasive v11 rocksmith 2014 dlc crack xbox “The greatest source of physician radiation exposure during cardiac catheterization comes from scatter radiation emitted from the patient, which itself is proportional to patient radiation dose,” wrote lead author Ryan D. Madder, MD, with Spectrum Health in Grand Rapids, Michigan, and colleagues. “Because greater radiation doses are required to produce adequate images in obese patients, greater amounts of scatter radiation are emitted, and consequently, the obesity epidemic has the potential to alter the occupational risks of physicians performing cardiac catheterization.”

Patients with BMIs above 40 were found to experience a 2.1-fold increase in radiation versus those with normal weight (BMI below 25), but the relative radiation increase was seven-fold for physicians treating those heavier individuals. This was even with the doctors following their standard protocol of having two shields placed between them and the patient in all cases, designed to protect both the upper and lower body.

crack for say the time dog the bounty hunter on crack “Physician radiation dose is not solely dependent on DAP (dose area product) but rather depends on other factors as well, including the distance between the physician and the patient, the degree of lead shielding, and the time the physician spends in the zone of scatter radiation,” the researchers wrote. “Thus, it is conceivable that if any of these other factors is unfavorably impacted by increasing patient BMI, then physician radiation dose may increase out of proportion to the DAP alone.”

Each one-unit increase in BMI was linked to a 5.2 percent higher radiation dose for the physician, despite interventional cardiologists more often using additional radiation-absorbing pads for heavier patients. Notably, the use of radiation-absorbing pads was linked to a 70 percent reduction in exposure in a multiple regression analysis, which also independently associated PCI and fractional flow reserve with a higher physician radiation dose.

They suggested operators be aware that obese patients may put them at risk of higher radiation exposure and be particularly vigilant about using protective shielding. Hospitals could also help by investing in the best fluoroscopy equipment, which may itself continue to improve and produce high-quality images at lower radiation doses.

Central adiposity would be expected to require more radiation for angiography than if the patients’ fat were more heavily distributed elsewhere.

Corindus’ technology recently facilitated the pst scanner keygen free download, during which an operator performed “tele-stenting” procedures on five different patients located 20 miles away. Eliminating operator radiation exposure from up-close procedures has been touted as one of the robotic platform’s benefits.
