A Factor Increasing Venous Contamination on Bolus Chase Three-dimensional Magnetic Resonance Imaging: Charcot Neuroarthropathy

Abstract

Background:The study aimed to evaluate the ratio of venous contamination in diabetic cases without foot lesion, with foot lesion and with Charcot neuroarthropathy (CN).Materials and Methods:Bolus-chase three-dimensional magnetic resonance (MR) of 396 extremities of patients with diabetes mellitus was analyzed, retrospectively. Extremities were divided into three groups as follows: diabetic patients without foot ulcer or Charcot arthropathy (Group A), patients with diabetic foot ulcers (Group B) and patients with CN accompanying diabetic foot ulcers (Group C). Furthermore, amount of venous contamination classified as no venous contamination, mild venous contamination, and severe venous contamination. The relationship between venous contamination and extremity groups was investigated.Results:Severe venous contamination was seen in Group A, Group B, and Group C, 5.6%, 15.2%, and 34.1%, respectively. Statistically significant difference was seen between groups with regard to venous contamination.Conclusion:Venous contamination following bolus chase MR was higher in patients with CN.

Charcot Neuroarthropathy and a New Sign: “Soft Tissue Contamination Sign of Foot or Ankle” on Bolus Chase 3-Dimensional Magnetic Resonance Imaging

“…We consider that this soft tissue contamination sign might be a specific sign for CN on the 3D MR angiography examination. Also, we showed venous contamination in 3D MR Imaging was more frequently detected in cases with CN (5). And according to this finding, we considered that the inflammatory process might play a prominent role in the pathogenesis of CN.…”

Pathogen-specific molecular imaging and molecular testing methods in the prognosis of the complicated course of diabetic foot syndrome, the risk of amputation, and patient survival

“…Важное значение в оценке анатомии и патологии сосудов стоп придается контрастной МР-ангиографии (кМРА). Преимущества кМРА перед цифровой субтракционной ангиографией (СА) у больных СДС состоят в визуализации большего числа стенозированных сосудов и одновременной отчетливой визуализации воспалительных осложнений -ОМ, абсцессов мягких тканей и свищей [13]. Однако кМРА уступает СА в оценке дистально расположенных сосудов, а также в ситуации критической ишемии.…”

“…Контрастная магнитно-резонансная ангиография также применяется для оценки уровня активности при остром течении стопы Шарко и мониторинга реакции на лечение с прогнозированием времени заживления раневых дефектов [1,3]. Показатели диагностической эффективности кМРА превосходят показатели КТ-ангиографии и дуплексного ультразвукового сканирования сосудов стоп при СДС [13].…”

Prevalence and risk factor analysis for the nonalcoholic fatty liver disease in patients with type 2 diabetes mellitus

“…Doppler sonography examination has emerged as the noninvasive imaging method of choice for evaluation of liver blood supply and some of liver parenchyma's disorders. [ 9 ] In addition, FGFL is another noninvasive test, performed by experienced medical doctors, to quantify liver fibrosis based on using ultrasound waves. However, abdominal US lacks the sensitivity required for mild steatosis analysis and requires significant knowledge and experience in analyzing the various ways NAFLD can present.…”
