Objective: The main objective of the current study was to examine the outcome of critically ill patients in relation to clinical and thoracic injuries. The secondary objectives were to assess the role of CT in the evaluation of the diaphragm and to provide an analysis of prognostic abilities with respect to diaphragm changes.
Methods: This single-center retrospective observational cohort study was conducted in the ICU of Târgu Mureș County Emergency Clinical Hospital, Romania. This study identified 52 critically ill blunted or penetrating chest trauma patients admitted to the ICU from 01 January 2021 to 31 December 2021. CT scan was used to identify thorax injuries and diaphragm thickness. The outcome of all patients was analyzed.
Results: Most of the patients experienced traffic accidents (44.23%) or falls (26.93%). The predominant characteristics associated with chest trauma were rib fractures (92.30%), lung contusions (63.50%), and pneumothorax (53.80%). The most common injury seen in the study was rib fractures, accounting for 92.30% of cases. This was followed by lung contusions, which were present in 63.50% of patients, and pneumothorax, which occurred in 53.80% of cases. It was examined ROC AUC for thickness of the right and the left diaphragm and severity scores. When assessing the thickness of the diaphragm in deceased and survivors, no statistically significant differences were found.
Conclusion: Although no significant differences were found regarding the prognosis between the survivors and the deceased, diaphragm thickness might potentially serve as a predictor for the severity of the injury.

Objective: To search for a dependency between blood Hounsfield Units values as measured by Computed Tomography and blood components with regards to hemoglobin oxygenated status, demographic data and acquisition parameters.
Methods: A retrospective study included a convenience sample of 144 SCJU patients who underwent routine thoracic CT examinations (Siemens Somatom AS 64 or 128 MDCT) in 2014 and had laboratory examinations done in nearby time. Variables included age, sex, mA, mV, aortic HU values, PA HU values, RBC, HTC, HGB, PLT, WBC blood sugar, PT and INR. Statistical analysis was performed using R version 3.1.1 and MedCalc 12.5 with a statistical significance factor of 0.05.
Results: The examined patients had an average age of 56.25, with a predominance of males (M:F=1.62). While there was a minor difference between HU values in Males vs Females (1.01 HU) it was proven as statistically significant (p=0.0051). No statistical significant difference between oxygenated/non-oxygenated blood (p=0.9636). Regression analysis found positive correlation between HU values and RGB, HGB and HCT with a significance level below 0.0001, the strongest being for the HGB level.
Conclusions: While HU values seem to carry multifactorial sources and the red blood cells being the most important an importance should be given to the fibrinoid plasma components which appear to bear negative impact.

Background: Quantitative assessment of body fat is important for the diagnosis and treatment of diseases related to obesity, Computed tomography (CT) becoming the standard procedure for measuring the abdominal fat distribution.
Material and method: The retrospective study included 111 inpatients, who underwent routine abdominal CT exams in the Radiology Laboratory of SCJU Tg.Mures (2013). MPR MDCT (SOMATOM AS 64) data was processed using a custom written MATLAB R2009b software, ImageJ being used for tracing of the visceral fat area (VFA). Patient data (including blood glucose, cholesterol and triglycerides) were analyzed using MO Excel and GraphPad Inprism5.
Results: Visceral Fat percentage varied in population from 14.59–68.69 (SD = 11.83) with significant difference between sexes (male vs. female, 46.98 vs. 31.62, p <0.05). Cholesterol values >220 mg% and triglycerides >150 mg% are significantly associated with the VF percent (p <0.05). Overall there is a weak correlation between the lab variables and the measured fat, the strongest one being between triglycerides and the VFA (r = +0.23) and between age and VFA percentage (certain samples).
Conclusions: The technique used should decreases the human error in marking of the fat areas providing a better estimation of the VF/VF percentage. CT measured VF relates with certain lab tests. Further analysis, is required for a better use of CT in obesity related pathology diagnosis and treatment.

Objective: We aimed to underline the surgical importance of the distances between the landmarks of the temporal bone, important for quantifying the benefits and disadvantages of two different cochlear implant techniques.
Methods: We have gathered all data from the Radiology Department in Emergency County Hospital in Tîrgu Mureș, namely computed tomography imagistic studies in order to perform the required measurements, according to pre-defined inclusion/exclusion criteria. The time interval was 5 months.
Results: The comparison between the sets of data shows a good match for the risk/benefit ratio for the two types of technique for cochlear implantation.
Conclusions: The middle cerebral fossa approach for the electrode insertion into the cochlea is a viable and needed surgical technique as the classic approach has reached its boundaries and new challenges appear. As surgical decisions are largely based on radiology data, our work underlines the importance of solving the borderline pathology, the extreme cases and the role of surgery in improving the quality of life for every patient with cochlear implant indication.
