Item Percepción de la satisfacción y calidad de atención de los pacientes en los servicios de rayos X, mamografía, tomografía computarizada y resonancia magnética en un centro privado de diagnóstico en la ciudad de Cuenca en el período agosto - octubre 2025(Universidad de Cuenca. Facultad de Ciencias Médicas, 2026-03-03) Maldonado Toledo, Romina Rebeca; Torres Vicuña, Karen Melissa; Astudillo Reyes, Adriana EstefaníaBackground: The evaluation of patient satisfaction and quality of care, through user perception, serves as an indicator that allows for the measurement and assessment of outcomes related to healthcare services provided in different areas of health care (1). Imaging studies are essential for the diagnosis and detection of various pathologies, as these procedures enable the visualization, analysis, confirmation, or exclusion of conditions that affect a patient's health and integrity (2). Objective: To determine patient perception regarding satisfaction and quality of care in the X-ray, Computed Tomography, Magnetic Resonance Imaging, and Mammography services of a private diagnostic institution during the period of August to October 2025, in the city of Cuenca, Ecuador. Method: Quantitative, observational, descriptive, cross-sectional study. The sample consisted of all patients who agreed to participate in the study and underwent one or more imaging procedures at a private diagnostic center in the city of Cuenca. The information obtained through the SERVQUAL (Service Quality Model) instrument was tabulated and analyzed according to the study variables. Results: A total of 398 patients were surveyed. The majority of participants were women (63.07%), with a predominance of patients between 19 and 60 years of age (72.29%). The most frequently performed imaging study corresponded to the X-ray service (42.71%). Across the five SERVQUAL dimensions, an average score higher than 4.43 was observed, indicating a high level of satisfaction with the imaging services.Item Prevalencia de litiasis renal diagnosticada mediante urotomografía simple en pacientes de 30 a 80 años, en Medimagen Cuenca - Ecuador, periodo enero 2023 - enero 2025(Universidad de Cuenca. Facultad de Ciencias Médicas, 2026-03-02) Macas Morocho, Karla Elizabeth; Ramírez Nieto, Roosvel Adrián; Solano Brito, Pablo JoséBackground: It is estimated that between 10% and 12% of the population has presented renal lithiasis at some point in their lives, being more predominant in men. (1)(2) The diagnosis of this disease has improved significantly with the use of advanced imaging techniques, with simple computed tomography urography (Uro-CT) being the method of choice due to its high sensitivity and specificity, offering a rapid and precise evaluation of the urinary tract, surpassing traditional methods such as plain radiography, ultrasound, and excretory urography. (3)(4) Objectives: To determine the prevalence of renal lithiasis diagnosed through simple Uro-CT in patients aged 30 to 80 years at Medimagen, Cuenca-Ecuador, period January 2023 - January 2025. Methods: Descriptive, cross-sectional study. Data were obtained from the review of imaging reports of simple Uro-CT studies from the Medimagen diagnostic imaging center. Results: A total of 392 radiological reports were analyzed, showing that the prevalence of renal lithiasis was 41.33%, corresponding to 162 patients, with the highest involvement in the age groups 30-40 years (35.80%) and 41-50 years (24.69%). It was also observed that this condition affects males slightly more (51.23%). The most frequent possible chemical composition among the renal lithiasis diagnoses was uric acid (37.65%), affecting the right kidney more (48.15%), with the distal ureter (32.72%) being the most affected location.Item Prevalencia de lesiones de menisco diagnosticadas mediante resonancia magnética de rodilla en pacientes de 20 a 60 años en el Hospital Universitario del Río, Cuenca, Enero 2021-Enero 2025(Universidad de Cuenca. Facultad de Ciencias Médicas, 2026-02-27) Maldonado Cajamarca, Dana Paula; Tepan Matailo, Ana Cristina; Pineda Alvarez, Rosario ElizabethBackground: Magnetic Resonance Imaging (MRI) has revolutionized musculoskeletal imaging since its introduction in the 1970s. The knee is one of the most frequently studied joints in the field of imaging. MRI is essential for evaluating meniscal injuries, offering superior image quality and diagnostic accuracy. (1) Objective: To determine the prevalence of meniscal injuries diagnosed by knee MRI in patients aged 20 to 60 years at Hospital Universitario del Río, Cuenca, from January 2021 to January 2025. Methods: This was a quantitative, descriptive, cross-sectional, and retrospective study. Knee MRI reports from patients aged 20 to 60 who attended Hospital Universitario del Río between January 2021 and January 2025 were reviewed. Imaging reports with a diagnosis of meniscal injury were included. Incomplete reports and those with pathologies unrelated to the focus of this study were excluded. The data obtained were analyzed using descriptive statistics to determine the prevalence of meniscal injuries. Results: Of the 597 imaging reports reviewed, 230 patients (38.5%) presented meniscal injuries, with a higher prevalence in males (28.8%). The most frequent age group was 41-50 years (11.6%). The most common type of meniscal injury was the horizontal tear, representing 39.1%. The medial meniscus was the most frequently affected site (52.6%). The right knee was the most commonly involved, with 57.8% of the cases.Item Prevalencia de discopatía degenerativa en columna lumbar diagnosticada por resonancia magnética simple en pacientes de 30 a 70 años en Medimagen, Cuenca - Ecuador, periodo enero 2023 - febrero 2025(Universidad de Cuenca. Facultad de Ciencias Médicas, 2026-02-27) Pogo Requenes, Heidi Gabriela; Reinoso Lasso, Angie Doménica; Solano Brito, Pablo JoséBackground: Degenerative disc disease is a condition characterized by the progressive wear of one or more intervertebral discs, especially in the lumbar region. (1) These alterations cause a reduction in the intervertebral space, narrowing the openings through which spinal nerves emerge, generating radicular compression. (2) Over time, this condition leads to dehydration and decreased height of the intervertebral discs, as well as changes in their density. (3) Currently, magnetic resonance imaging is the standard method for evaluating degenerative disc disease due to its high sensitivity and specificity. (4) Objective: To identify the prevalence of degenerative disc disease in the lumbar spine diagnosed through simple magnetic resonance imaging in patients aged 30 to 70 years at Medimagen, Cuenca - Ecuador, during the period January 2023 - February 2025. Methods: A descriptive, cross-sectional study was carried out. Data were obtained through the review of simple lumbar spine MRI imaging reports performed at Medimagen. Results: Of the total of 873 imaging reports, the prevalence of lumbar degenerative disc disease was 97.3%, with the highest involvement in the age group 30-40 years (28.2%) and a higher percentage in females (49.4%). Among the pathologies associated with degenerative disc disease, the most frequent was disc degeneration (67.4%). Likewise, the lesions involved more than one segment of the lumbar spine (88.3%), and 64.0% of the patients did not present any Modic changes.Item Prevalencia de esteatosis hepática diagnosticada por ecografía abdominal en pacientes de 20 a 80 años del Centro Radiológico Medimagen, Cuenca, período abril 2024- abril 2025(Universidad de Cuenca. Facultad de Ciencias Médicas, 2026-02-26) Cojitambo Maldonado, Julissa Fabiana; Astudillo Reyes, Adriana EstefaníaBackground: Hepatic steatosis is defined as the excessive accumulation of fat in the liver. In most cases it is asymptomatic, which hinders its diagnosis in its early stage (1). The World Health Organization (WHO) reported that one in three adults worldwide present this condition, and that 10% of infants are also affected (2). In Latin America, its prevalence reaches 27,45%, while in Ecuador hepatic steatosis is among the ten leading causes of mortality (3) (4). Abdominal ultrasound is the study of choice for the detection of hepatic steatosis due to its sensitivity and specificity (5). Objective: To determine the prevalence of hepatic steatosis diagnosed by abdominal ultrasound in patients aged 20 to 80 years at Centro Radiológico Medimagen, Cuenca, during the period April 2024-April 2025. Methods: Descriptive crosssectional study. Data were collected from imaging reports of patients aged 20 to 80 years who attended Centro Radiólogico Medimagen, Cuenca, during the period April 2024-April 2025. A total of 666 imaging reports were obtained. Results: The prevalence of hepatic steatosis was 56.3%, representing 375 of the 666 abdominal ultrasound imaging reports; it was more prevalent in females with a 36.2% and in the 50-59 age range with 13.2%, with a higher presence of grade II (57.6%). Conclusion: The prevalence of hepatic steatosis in the study population represents 56.3%.Item Prevalencia de esclerosis ósea de columna lumbar y rodillas diagnosticada mediante rayos X en pacientes de 21-90 años en la Clínica Santa Ana Cuenca-Ecuador periodo Agosto 2022 - Abril 2025(Universidad de Cuenca.
