Objective: Computed tomography angiography (CTA) examinations are performed to diagnose blood vessel anomalies. However, this examination results in a significant radiation dose being received by the patient. Local diagnostic reference levels (DRLs) are necessary for determining the extent of radiation dose during examinations. Therefore, the main...

Background Breast cancer remains a significant global health concern, with early diagnosis and risk factor identification crucial for improving outcomes. Diffusion-Weighted Imaging (DWI) and Apparent Diffusion Coefficient (ADC) measurements have emerged as promising tools in breast cancer diagnostics. However, the influence of hormonal status on th...

Degenerative spine disease is a significant health concern in animals due to its impact on daily activities such as movement, balance, and thermoregulation. Early diagnosis is essential for effective management and treatment, with MRI playing a crucial role in identifying degenerative changes. Advanced MRI sequences, particularly Diffusion Weighted...

Background: Stature estimation is crucial in forensic anthropology for victim identification. While long bones are traditionally used, exploring alternative skeletal elements could enhance accuracy and applicability in various forensic scenarios. Objective: To evaluate the potential of the femur, tibia, fibula, pelvis, sacrum, and thoracolumbar ver...

Purpose: Computed tomography angiography (CTA) is a non-invasive procedure to evaluate vascular anomalies. However, the high radiation dose related to the examination is a concern due to its associated cancer risk. Therefore, this study aims to investigate the effect of low tube voltage CT lower limb angiography with aortogram (CTLLA) on radiation...

Purpose Medical technology has gone a long way in diagnosis and characterization of breast tumors. Diffusion-weighted MR imaging is the state of the art for breast screening and diagnosing. The aim of this meta-analysis is to evaluate the diagnostic performances of diffusion-weighted MR imaging in characterization of breast lesions with different b...

Background: Globally prostate cancer is one of the most prevalent cancer among men and a leading cause of morbidity and mortality, especially in a developing country, which is mainly due to lack of knowledge and awareness regarding the screening of prostate cancer. The main objective of this review and meta-analysis is to evaluate the knowledge, a...

Background: High-resolution CT (HRCT) thorax has increase demand due to its advantage in diagnosing chronic respiratory diseases. The feasibility of matrix size with different tube voltage in the HRCT protocol of thorax is unknown. Therefore, this study aimed to compare the effect of matrix sizes and tube voltage on image quality and radiation dose...

Introduction: Radiation exposure during the CT examination has always been a concern due to its associated cancer risk. The guidelines suggest the optimization of radiation dose reduction. Therefore, this study aims to determine the feasibility of dose reduction strategies on radiation dose reduction using a phantom. Methods: Head and body phantoms...

Objective: The objective of this study was to estimate the entrance surface radiation dose to the thyroid region in a computed tomography (CT) brain scan.Methods: Unfors Multi-O-Meter equipment was used to measure the entrance surface at the thyroid region of adult patients ranging from 18 to 70 years of age. A total of 115 patients were included i...

Objectives: The main objective of the study was to determine the normal subcarinal angle (SCA) in an adult patient, to compare the relationship of SCA with patient gender and age, and to correlate the SCA with body mass index (BMI).Methods: A total of 193 subjects (109 males and 85 females) in the age group of 20–60 years scheduled for computed tom...

Introduction: Sacral colpopexy is the gold standard procedure for pelvic organ prolapse. During sacral colpopexy, various complications such as haemorrhage can occur. Careful dissection of presacral space is essential to minimize complications. Aim: The aim of the study was to compare patient age and Body Mass Index (BMI) with Computed Tomography (...

The objective of the study was to estimate the normal upper and lower limit cut off value of the different dimensions of maxillary and frontal sinus, also to determine the influence of gender in the obtained variables and to observe the effect of nasal septal deviation on maxillary sinus. A perspective observational study was carried out and a tota...

Endoscopy of the lumbar sub-arachnoidal space is named thecaloscopy, which has been used for diagnostic and therapeutic purposes. The understanding of the anatomic dimensions of this region is useful for the atraumatic use of flexible endoscopes. Furthermore, by using MRI the determination of anatomic values of the sacral spinal canal is possible w...

MRI plays a significant role in modern forensic anthropology to solve certain queries of legal / public concern. The objective of our study was to determine the sexual dimorphism of the first sacral vertebra (S1) in south Indian adults and to compare the differences in sacrum measurement of south India with literature. MRI of lumbo-sacral region wa...

In recent years, much attention has been given to the role of CT in detecting and quantitating respiratory health problems. Approximately 1.25 billion people smoke cigarettes daily worldwide (2). Lung density changes are expected for smokers over a period of time. Medical imaging comprises different imaging modalities and processes to image human b...
