“…5 At our institution, a single-pass split-bolus CT of thorax and abdomen is applied to the majority of trauma patients. 6 For this type of thoracoabdominal CT scan, data from our National Radiation and Nuclear Safety Authority report an average dose of 14.2 mSv. 7 In cases of pelvic or urinary tract injury, further arterial or delayed phase scans are obtained and increase radiation dose is administered to the patient.…”

Background Radiation-related cancer risk is an object of concern in CT of trauma patients, as these represent a young population. Different radiation reducing methods, including iterative reconstruction (IR), and spilt bolus techniques have been introduced in the recent years in different large scale trauma centers. Purpose To compare image quality in human cadaver exposed to thoracoabdominal computed tomography using IR and standard filtered back-projection (FBP) at different dose levels. Material and methods Ten cadavers were scanned at full dose and a dose reduction in CTDIvol of 5 mGy (low dose 1) and 7.5 mGy (low dose 2) on a Siemens Definition Flash 128-slice computed tomography scanner. Low dose images were reconstructed with FBP and Sinogram affirmed iterative reconstruction (SAFIRE) level 2 and 4. Quantitative image quality was analyzed by comparison of contrast-to-noise ratio (CNR) and signal-to-noise ratio (SNR). Qualitative image quality was evaluated by use of visual grading regression (VGR) by four radiologists. Results Readers preferred SAFIRE reconstructed images over FBP at a dose reduction of 40% (low dose 1) and 56% (low dose 2), with significant difference in overall impression of image quality. CNR and SNR showed significant improvement for images reconstructed with SAFIRE 2 and 4 compared to FBP at both low dose levels. Conclusions Iterative image reconstruction, SAFIRE 2 and 4, resulted in equal or improved image quality at a dose reduction of up to 56% compared to full dose FBP and may be used a strong radiation reduction tool in the young trauma population.

“…A recent study (58) in which a triple split bolus technique (obtaining arterial, venous, and delayed images in a single imaging set) was used with portal venous phase CT in 35 patients with acute traumatic injury showed no significant difference in image quality or injury diagnosis. CT cystography can be performed to assess bladder integrity.…”

After experiencing blunt or penetrating trauma, patients in unstable condition who are more likely to die of uncorrected shock than of incomplete injury repairs undergo emergency limited exploratory laparotomy, which is also known as damage control surgery (DCS). This surgery is part of a series of resuscitation steps, with the goal of stabilizing the patient's condition, with rapid surgical control of hemorrhage followed by supportive measures in the intensive care unit before definitive repair of injuries. These patients often are imaged with multidetector CT within 24-48 hours of the initial surgery. Knowledge of this treatment plan is critical to CT interpretation, because there are anatomic derangements and foreign bodies that would not be present in patients undergoing surgery for other reasons. Patients may have injuries beyond the surgical field that are only identified at imaging, which can alter the care plan. Abnormalities related to the resuscitation period such as the CT hypoperfusion complex and ongoing hemorrhage can be recognized at CT. Familiarity with these imaging and clinical findings is important, because they can be seen not only in trauma patients after DCS but also in other patients in the critical care setting. The interpretation of imaging studies can be helped by an understanding of the diagnostic challenges of grading organ injuries with surgical materials in place and the awareness of potential artifacts on images in these patients.

“…"Abdominal boluses" help to monitor the health of the animal and its metabolism. [2] The financial benefit of their use is mainly in the assessment of the quality of nutrition and the fact that the animals receive medical assistance when a minimal problem appears -prevention. In real terms, this can be measured to reduce the cost of treating and killing part of the herd up to 30% of the value of the animals.…”

Today, the world is experiencing an environmental crisis that is far more dangerous than an economic one. The search for and implementation of innovations that support business should also be consistent with their ecological effect. Raising animals for food originated more than 8,500 years ago, and today meat is part of the diet of most people. Beef farming has reached the stage where implementing digital innovations is a necessity. Unfortunately, when implementing new solutions, the effect on nature is often not evaluated. The environmental impacts may be irreversible or difficult to reverse and may require a much higher cost to remedy. The purpose of the research is to compare the profitability of the implemented solutions, in relation to the environmental problems. The results of the study of some of the most widespread innovations can be systematized in several directions. The implementation of animal control systems on pastures could destroy the natural habitat of wild animals and technical solutions should be sought that reduce these impacts. Tracking the behavior and collecting biometric data from the animals can also be done with non-invasive methods, which will be much more humane and will not disturb the ecological balance in relation to the bees. The main problems are related to the access of wild animals to food and water in control systems by restricting pastures and the use of certain frequencies to transmit the biometric data of the animals and their impact on both farmed animals and bees and other species in the wild. In conclusion, the profitability of beef pasture animal husbandry has the possibility to increase without significant damage to nature, if it is approached relatively individually to each specific regional project in Bulgaria.
