Purpose: The main purpose of this study was to evaluate the intervertebral disc height and intervertebral disc degeneration between the normal group and the group with disc herniation at the level of the L4–L5 intervertebral disc by MRI using the Pfirrmann grading system. Materials and Methods: 385 patients were included in this study. MRI images were reevaluated and intervertebral disc heights were measured from the anterior, middle and posterior segments. Researchers divided disc pathologies into two groups. In the non-herniated group; normal or bulging ones; in the herniated group, they included those with protrusion or extrusion. Results: 385 lumbar MRI examinations meeting the study criteria were included in study. There were 56.9% (219/385) females and 43.1% (166/385) males in the study. For the whole patients in the study group, the intervertebral disc height values at the L4–5 level were measured as 12.34 mm, 11.58 mm, and 7.60 mm in the anterior, middle, and posterior localizations, respectively. Conclusions: At the L4–5 level, the height of the disc distances in the herniated group was lower than in the normal group. The Pfirrman score was found to be higher in the herniated group in terms of disc degeneration compared to the normal group.

Detection of tracheal branching with computerized tomography: The relationship between the angles and age-gender

Prevalence of mesenteric panniculitis in patients with urinary system calculi and identify factors, such as hydronephrosis and calculus location, that might be associated with the presence of mesenteric panniculitis. Materials and Methods: In this retrospective observational study, the prevalence of mesenteric panniculitis was determined in 692 patients with urolithiasis using non-contrast-enhanced computed tomography imaging between 2017 and 2020. The grade of hydronephrosis and the level of urinary calculi were recorded for each patient, and statistical analysis was performed to assess the link between these features and mesenteric panniculitis. Results: The prevalence of mesenteric panniculitis in patients with urolithiasis was 6.35% and it was associated with the presence of hydronephrosis. It was more common in patients who had both ureterolithiasis and nephrolithiasis with no statistically significant difference regarding in age, gender, or the presence of either only nephrolithiasis or only ureterolithiasis. Conclusion: Mesenteric panniculitis is more common in patients with both ureterolithiasis and nephrolithiasis and can be easily diagnosed with non-contrast computed tomography imaging. Because the mesentery and urinary system share a common lymphatic drainage system, increased lymphatic drainage due to hydronephrosis has been shown to contribute to the development of mesenteric panniculitis.
