Diagnostic value of ultrasound and contrast‐enhanced ultrasound in septic acute kidney injury

Abstract

Purpose This study aimed to explore the clinical value of ultrasonic Doppler examination and contrast‐enhanced ultrasound (US) in the circulation of septic acute kidney injury (AKI). Methods Patients with intensive care unit‐related infection were divided into AKI group and control groups. The AKI group was divided into three subgroups according to the serum creatinine value: stage 1, stage 2, and stage 3. Relevant parameters and blood flow of the renal artery were measured, and further contrast‐enhanced US was performed and time‐intensity curve was analyzed. Results The renal blood flow (RBF) and time‐averaged velocity decreased significantly in the AKI group compared with the control group (p = .021 and p = .001). The peak value decreased and time to peak (TTP) prolonged in the AKI group (p < .001). With the aggravation of the disease, the RBF decreased slightly among subgroups (p = 0.124). However, the peak value gradually decreased and the TTP prolonged (all p < .05). The multiple linear regression model showed that only PI, RI, and TTP were independently and linearly correlated with the serum creatinine value. Conclusions Doppler US and contrast‐enhanced US are of great help in the detection of condition changes and prognosis of patients with sepsis‐induced AKI.

Acute Kidney Injury in Patients With Acute Leukemia After Hematopoietic Stem Cell Transplantation: A Series of Clinical Cases

“…Oncology and radiology of Kazakhstan, №3 (65) 2022 The presented ultrasound results reflect the kidney size changes in AKI similar to those reported by P.Q. Liu [12]. A systematic review by S. Ninet al showed that an elevated resistance index could predict persistent AKI in critical patients [13].…”

The value of ultrasound in combination with 99mTc-MIBI imaging department of ultrasound medicine, for the diagnosis of ectopic parathyroid glands in the thyroid gland in patients with secondary hyperparathyroidism

“…Inflammatory cervical lymph nodes or retroconvex thyroid nodules may also appear as radioconcentrated foci, making them prone to false positives, [28] and 99m Tc-MIBI imaging is unable to clarify the anatomical relationship between foci and surrounding tissues, whereas conventional ultrasound can clearly visualize the parathyroid glands with a maximum diameter of 3-5 mm and their blood flow distribution characteristics, and can also clearly visualize the cystic foci and the anatomical relationship with the surrounding tissues, which compensates for the deficiencies of 99m Tc-MIBI imaging. Zhang et al ( 2006) and Liu et al (2004) [29,30] indicated that the detection rate of ectopic parathyroid lesions by ultrasound combined with 99m Tc-MIBI dual time-phase imaging was significantly higher than that of any single examination method, such as ultrasound, CT and MRI. In this study, 5 patients with ETPG had a total of 21 parathyroid glands, and 99m Tc-MIBI imaging showed 14 (Fig.…”

Diagnostic value of multi-parameter ultrasound evaluation in sepsis complicated by acute kidney injury

“…Reportedly, MPUS has been used to predict hydronephrosis [ 19 , 20 ]. Meanwhile, some studies have predicted kidney injury using MPUS [ 21 , 22 ]. However, the diagnostic efficacy of MPUS in patients with sepsis-induced AKI remains unclear.…”
