For students to better manage their curriculum and achieve learning objectives, time management behaviors or skills are argued to improve the positive academic output. The aim of the study is to find the impact of time management on the academic performance of students among the diagnostic radiology technology students at KAU. This study had a cross-sectional survey-based study design. It was conducted among students of diagnostic radiology technology department at King Abdul-Aziz University from Sep. 2020 to Feb. 2021. For this study, 152 students were targeted among which 142 completed the questionnaire, making the response rate of 93.4%. Among 142 participants, 75 (52.8%) were females and 52 (36.6%) were in the 2018 batch. Majority of the students i.e., 107 (75.4%) had GPA between 4.5-5 in 2020. Whereas, 37.3% agreed or strongly agreed that they manage their time. Here, 69.2% students with 4.5-5 GPA strongly agreed that they meet their deadline (p value = 0.005) and 36.7% students with 4-4.5 GPA strongly believed that their academic performance decreased due to mis planning (p value = 0.005). Around 71 (66.3%) students with 4.5-5 GPA agreed or strongly agreed to make to do list or calendar (p value 0.047). In conclusion, according to student's perception, preplanning their studies had been beneficial for their academic performance. However, less than half of the students agreed that they manage their time.

Purpose: To evaluate the amalgamation of scintigraphy and sonography techniques in prognosticating renal disease. Methods: All the patients were subjected to renal scintigraphy while 68 patients underwent renal ultrasonography. Ninety-six patients' imaging data was statistically analyzed including 43 females and 53 males. Renal U/S reported anatomical renal anomaly in 94.1% of patients versus 85.4% detected by scintigraphy. There were 41 patients out of 68 diagnosed with hydronephrosis and 21 of them were suffering from mild hydronephrosis as suggested by U/S imaging. The data were statistically analyzed using SPSS 21 software. Results: Renal scintigraphy of 41 hydronephrotic patients validated that 19 patients had non-obstructive bilateral pelvic dilation while the remaining 22 with mild to severe obstruction. Ultrasonography diagnosed 4 patients with renal obstruction. Conversely, renal scintigraphy validated 2 of them with renal obstruction based on renal function. Conclusions: Renal scintigraphy is not significant in diagnosing kidney disease; rather this is a vibrant imaging tool providing supplementary data based on renal function. An effectively targeted intervention regime can be achieved by correlating renal scintigraphy and renal ultrasonography results to minimize renal disease incidence.

Objectives:To identify the occurrence rate of thyroid ultrasound abnormalities in asymptomatic subjects, and describe the features of detected nodules among university students.Methods:The study is based on an observational research design that was conducted from April 2015 to May 2015. The study included 166 individuals, aged between 19 and 23 years. The subjects had their glands examined by ultrasound (US) scanning, using Philips ultrasound machine (5-12 MHz linear transducer).Results:We recruited 90 (57.8%) females and 76 (42.2%) males without any indications of thyroid disease. Data estimated that 41 (24.7%) subjects had positive results on thyroid disease screening, 24 (70.6%) participants had solitary nodules, and 10 (29.4%) had multiple nodules. Thirty-four subjects revealed nodular presentation in the screening, among which 24 (70.6%) indicated solitary nodules and 10 (29.4%) had multiple nodules. Among 3 subjects, who indicated hypoechoic nodules, 2 (66.7%) underwent US-fine needle aspiration biopsy and received histological confirmation that they had papillary carcinomas.Conclusion:Ultrasonography is a useful and effective technique for screening thyroid related diseases, and can be utilized as a routine practice for general population screening.

Background:Obstructive uropathy is a common public health issue that requires imaging research for providing necessary information. The data is important for determining treatment options, and may influence selective management choices.Objective:The aim of the study is to determine whether magnetic resonance urography or computerized tomography urography is the best imaging modality among patients with suspected obstructive uropathy.Methods:Seventy patients; referred from the emergency department for the evaluation of renal colic or hematuria that highly suggested urinary tract abnormalities, were prospectively enrolled. Thirty five women and 35 men were categorized with a mean age of 43.52 years and the mean body weight of 61.31 kg. All participants underwent abdominal ultrasonography and clinical examination to detect the causes of urinary obstruction. Pregnant women were excluded from the study. Both magnetic resonance urography and computerized tomography urography were performed within 30 days of each analysis.Results:Only 54.3% of the participants had urinary stones. Mean size of the renal stone was 11 mm; while mean size of the ureteral stone was 3.8 mm. The approach of magnetic resonance is not only limited to diagnosis, but is also effectively involved in the real time investigations. MRU has more reliability in terms of the diagnosis and anatomic presentation of the kidneys along with the vasculature. All cases of urinary stones were detected by computed tomography (100%); whereas, 78.9% cases were detected by magnetic resonance urography.Conclusion:Computerized tomography urography is more sensitive in detecting kidney stones; whereas, magnetic resonance urography is better in detecting pathology behind the development of kidney stones.

The effectiveness of diethylenetriamine pentaacetic acid scan is regularly monitored for the assessment of any potential modifications in treatment responses or kidney functions in the pediatric population. This study attempts to compare the usefulness of diethylenetriamine pentaacetic acid and ultrasound imaging of renal disorders among paediatric patients. A retrospective observational study was conducted by enrolling 106 children. The demographic details such as: participant's age, gender, and the history of renal disease of each patient were recorded. Patients were administered radiopharmaceuticals in a fixed dose and were later subjected to computed tomography (CT) scan. The obtained data was analysed using descriptive statistics. Findings indicated increased sensitivity for CT (61.20%); whereas, a major decrease in specificity (23.68%) was observed. Comparison of Single-photon emission CT (SPECT) and CT findings revealed the increased sensitivity (90.90%) for ultrasound; whereas, there was a slight decrease in the specificity (40%) for SPECT. However, SPECT findings show 91% sensitivity among patients with 71.42% positive predictive value. Moreover, an increase in sensitivity for CT (61.20%), followed by a major decrease in specificity (23.68%) was observed. Ultrasonography has been proved to be the safest and the most effective method for the diagnosis and the treatment of most renal disorders, due to the higher predictive value of SPECT scans. It is thus suggested that patients with ureteral calculi should be diagnosed with renal scintigraphy and unenhanced helical computerized tomography.

Background: With the evaluation of focal epi-cardial coronary stenosis and non-obstructive atherosclerosis, the cardiac scans play significant role in diagnosing coronary artery disease (CAD). Moreover, the advancements in the imaging techniques leading to improved risk assessment and timely therapies helps in early diagnosis of CAD with greater accuracy. Aims: To evaluate the role of cardiac scan in diagnosing CAD. Methods: Recruited 100 individuals without any history of CAD that refers to the assessment of suspected angina conducted the prospective study. Electrocardiogram (ECG) findings assisted in the evaluation of left bundle branch blockage, abnormalities of ST segment, and pathological Q waves. Results: The results depicted negative N.M findings among 38 respondents; whereas, ischemia and myocardial infarction was diagnosed in 26% and 19% of the respondents, respectively. Majority of the males (59) were positive in contrast to 37 females with positive results. Similarly, 24 respondents were presented with mild dilated left atria (LA), 37 respondents suffered from impaired relaxation pattern of left ventricular (LV) diastolic filling; while, 40 of the respondents had normal global LV systolic function. Conclusion: The study results have concluded that noninvasive, low-risk, and cost-effective technique like ECG is beneficial important advancement in the diagnosis of CAD.

Purpose: The study aims to investigate the specificity, sensitivity, and accuracy of nuclear medicine, CT scan, and ultrasonography to diagnose the disorders related to the thyroid gland. Methodology: The study is based on the retrospective approach of recruiting 52 patients suffering from thyroid disorders. The demographic details of each patient have been recorded. Moreover, the results of previously conducted nuclear medicine scan, CT scan, and ultrasound have also been assessed. The findings of all the tests have been compared to evaluate and compare their sensitivity, specificity, and accuracy. Results: A total of 52 patients were recruited for the study among which 41 were female and 11 were males. The findings of SPECT and MRI were compared, which revealed that MRI possessed 38.8% sensitivity and 22.22% specificity. As compared to the findings of CT scan, increased specificity (71.42%) and sensitivity (70.96%) have been identified in MRI. Conclusion: There is an increase in the sensitivity and specificity of MRI outcomes as compared to the nuclear medicine and CT scan.

Background: Cardiac disorders are the leading causes of morbidity and mortality globally. Aim: The current study aimed to compare the effectiveness of echocardiographic and scintigraphy investigation in cardiovascular disorders detection and evaluation, including ischemic heart disease (IHD) diagnosis at King Abdulaziz University in Saudi Arabia. Methods: 157 patients (male/ female: 68%/32%; mean age 64 ± 0.83 years) were included in the report in the current study. All subjects underwent gated myocardial perfusion scintigraphy and standard Echocardiography. Results: About 84% of cases were diagnosed with any types of cardiac disorders by Echocardiography, whereas through scintigraphy, 61% of patients were detected cardiac disorders. The age stratification did not impact the prevalence of cardiac disorders detected by them. Scintigraphy showed a higher detection rate (59%), while only 29% of cases were detected with IHD by eco-cardiograph. Conclusions: In conclusion, both techniques, namely standard Echocardiography, and myocardial scintigraphy, are useful in the evaluation and detection of cardiac disorders in patients having any type of cardiac problems. Both investigations showed a differential pattern in cardiac disorders diagnosis with a particular focus on IHD. Gender differences and age stratification also contributed to this differential pattern of diagnosis. Trial Registration: The research doesn't include experiments in humans or animals. It is a retrospective study for data record review as an observational study, so no trial registration is required.
