Abstract
In this study, the sinogram affirmed iterative reconstruction (SAFIRE) technology combined with low-dose computed tomography (CT) scanning technology was applied to scan patients with cerebral hemorrhage to evaluate the application value of this combined technology in the diagnosis of patients with cerebral hemorrhage. 132 patients with cerebral hemorrhage admitted to the hospital were selected randomly as the research objects in this study. According to the patients’ wishes, all of them were rolled into an experimental group and a control group. Besides, patients who were willing to use low-dose CT imaging scanning technology based on the SAFIRE algorithm were classified into the experimental group, and those who received simple low-dose CT scans were classified into the control group. Subjective score, objective score (mean CT value), image noise (SD), signal-to-noise ratio (SNR), and contrast-noise ratio (CNR) were used to analyze and compare the two groups of detection methods. The results showed the following: (1) The average result of CT images was 4.05 ± 0.28 points for the control group and 4.43 ± 0.59 points for the experimental group. According to the classification, the excellent and good rates of the experimental group (89.9%) were markedly higher than the rates of the control group (65.8%), with a statistically obvious difference ( P < 0.05). (2) The standard deviation (SD), image signal-to-noise ratio (SNR), and contrast-noise ratio (CNR) results of gray matter, white matter, and cerebral hemorrhage lesions of patients from the experimental group were better than those of the control group, and the differences were statistically significant ( P < 0.05). In conclusion, the image quality of a low-dose CT scan reconstructed by the SAFIRE algorithm was superior to that of a simple low-dose CT scan. In other words, the image quality of CT images could be guaranteed by the SAFIRE technology under the condition of reducing radiation dose. It enabled patients with cerebral hemorrhage to carry out diagnostic examinations with guaranteed accuracy under the risk of low radiation and provided better imaging services for patients with cerebral hemorrhage.
Highlights
Cerebral hemorrhage is a cerebrovascular disease that refers to the bleeding caused by the rupture of the blood vessels of the nontraumatic brain parenchymal tissue, which is a more common clinical disease [1]. e main cause of cerebral hemorrhage is the pathology of cerebrovascular tissue, which is closely related to factors such as hyperlipidemia, diabetes, high blood pressure, aging of blood vessels, and smoking [2]
Patients suffering from intracerebral hemorrhage often take emotional excitement or excessive exertion as the inducement, and there is a very high mortality rate in the early stage of the disease, while most of those who survive will have sequelae to varying degrees [3,4]. is disease accounts for 20%-30% of all stroke patients and is characterized by rapid onset, with the mortality rate of patients in the acute stage reaching 30%-40% [5,6]. erefore, accurate and timely clinical diagnosis is essential
79 were male patients and 53 were female patients; they were 35–75 years old, with an average age of 56.67 ± 3.31 years old. en, all patients were divided into the experimental group and the control group based on their wishes. 59 patients who were willing to be examined by the low-dose computed tomography (CT) imaging technology based on the sinogram affirmed iterative reconstruction (SAFIRE) algorithm were assigned to the experimental group
Summary
Cerebral hemorrhage is a cerebrovascular disease that refers to the bleeding caused by the rupture of the blood vessels of the nontraumatic brain parenchymal tissue, which is a more common clinical disease [1]. e main cause of cerebral hemorrhage is the pathology of cerebrovascular tissue, which is closely related to factors such as hyperlipidemia, diabetes, high blood pressure, aging of blood vessels, and smoking [2]. E main cause of cerebral hemorrhage is the pathology of cerebrovascular tissue, which is closely related to factors such as hyperlipidemia, diabetes, high blood pressure, aging of blood vessels, and smoking [2]. E sinogram affirmed iterative reconstruction (SAFIRE) algorithm is a new iterative reconstruction algorithm developed by Siemens, which is an iterative reconstruction algorithm based on the original data [11]. It can extremely reduce the noises of CT images and has a significant effect on the removal of spiral CTartifacts. Related studies have proved that the improvement of SAFIRE technology can decrease the CTscan dose without increasing the noise of the CT image, and the impact on the image quality is relatively small [13]
