Abstract
This work aimed to explore the application value of intelligent region of interest (ROI) detection algorithm in evaluating renal dynamic imaging information data of renal function in patients with chronic heart failure (CHF). 52 patients with CHF were selected as the research objects and grouped according to the level of renal function into an experimental group (14 cases) and an observation group (38 cases). In addition, 10 healthy people were selected as the research objects, as the control group. Different calculation methods of glomerular filtration rate (GFR) were used to evaluate the renal function of patients, and the ROI detection algorithm-assisted delineation was compared with traditional manual delineation. It was found that the GFR of the experimental group calculated by different methods was 52.58 mL/min/1.73m2 and 43.77 mL/min/1.73m2, respectively, which was significantly lower than that of the observation group ( P < 0.05 ), and that in both groups was lower than that of the control group ( P < 0.05 ). In addition, the unilateral renal function values of the two auxiliary delineations were both 13.61 mL/min/1.73 m2, while the results of the two manual delineations were significantly different ( P < 0.05 ). Therefore, renal dynamic imaging based on the ROI detection algorithm to evaluate the renal function of CHF patients showed a great improvement in effectiveness, sensitivity, stability, and efficiency compared with the traditional manual delineation, which was worthy of clinical promotion.
Highlights
Heart failure refers to the dysfunction of the systolic and diastolic functions of the heart caused by various cardiovascular diseases
A total of 14 patients with split renal function (SRF) < 30 mL/min/ 1.73 m2 were selected as the experimental group; a total of 38 cases with 30 mL/min/1.73 m2 < SRF
10 healthy people were selected from the hospital database as the control group, including 5 males and 5 females, aged from 35 to 54 years, with an average age of 44 ± 10.82 years. is study had been approved by the Ethics Committee of the hospital, and the patients and their families had understood the situation of the study and signed the informed consent forms
Summary
Heart failure refers to the dysfunction of the systolic and diastolic functions of the heart caused by various cardiovascular diseases. Almost all cardiovascular diseases can induce heart failure [4, 5], and some common factors can lead to heart failure, including respiratory tract infection, severe arrhythmia, excessive cardiac load, and excessive emotions, which will all change the structure and function of the myocardium, resulting in insufficient ventricular pumping function and filling capacity [6, 7]. Heart failure can cause dysfunction of various organs such as the kidneys, lungs, and liver, while abnormal organ function will further aggravate heart failure [8–10]. In the working mechanism of kidney, the filtration function of glomerular plays the most important role. Glomerular filtration rate (GFR) is an important and sensitive evaluation data in renal function evaluation. Renal dynamic imaging is commonly used to measure the glomerular filtration level [13, 14]
