To most people, pearls are considered precious gems, and are among the most popular jewels in the world. It should not be surprising that physicians consider a priceless bit of knowledge about their specialty a "pearl". For the diagnostic radiologist, a pearl may be the formerly elusive insight or fact that paves the way for a correct diagnosis or deeper understanding of a radiologic image. A traditional component of radiology education, pearls are considered on a par with elements such as the teaching file or lecture series. Pearls have also been a mainstay of www.CTISUS.com, where we post approximately 150 to 300 new pearls each month. In this app, we present pearls across 29 of the most popular categories derived from the literature or our imaging experiences. The app also provides a search feature to enhance user interactivity. We look forward to sharing these new insights with you on the latest version where we present literally thousands of pearls.

Developmental Dysplasia of the Hip (DDH) encompasses a spectrum of conditions where the hip joint is improperly formed, ranging from a mild acetabular shallowness to full dislocation. Early detection of DDH is crucial for effective management and prevention of long-term complications such as pain, limited mobility, or early-onset osteoarthritis. Ultrasonography, rather than X-ray, is the preferred method for diagnosing DDH in infants, especially under the age of 6 months. Ultrasound provides a non-invasive and radiation-free way to visualize the soft tissues, cartilage, and bones in real time. The Graf method is the most widely used technique, where two critical angles—alpha (α) and beta (β)—are measured to assess the development of the acetabulum and classify the hip's condition.This application is designed to aid healthcare professionals—especially radiologists, orthopaedic surgeons—in evaluating DDH by calculating the alpha (α) and beta (β) angles quickl from saved ultrasound images of the patient hip. Provide instant visual feedback by color-coding the angles:Alpha angle (α): red, Beta angle (β): yellow. Automatically also classify the hip joint based on the Graf method Type I,Type IIa/b,Type IIc,Type III, helping clinicians to have a quick glimpse and visualise the relationship between the angles ,real time.Healthcare professionals, particularly in busy departments, can save significant time by quickly loading ultrasound images and automating angle calculations, identify abnormal hips on the go . App can also be used as a training tool for medical students, residents, and junior clinicians, teaching them how to recognise key landmarks, make accurate measurements, and classify DDH using ultrasound images. By rapid visually displaying the measurements on the screen and generating easy-to-understand images, app helps clinicians explain the condition and its severity to parents. App offers α and β angle measurement by dragging points on the ultrasound image to key anatomical landmarks, forming lines that define the acetabular roof and cartilaginous roof. The app automatically calculates the angles and classifies the hip condition based on these measurements in real-time. Important feedback that help allow the user to adjust draggable points and see immediate changes in the angle values helping to fine-tune the position of the lines and target the preferred anatomical landmarks of the ultrasound image more efficiently. User-friendly interface, and reliable classification system based on Graf’s classification that streamline the diagnostic process, and improved overall workflow in clinical practice. Disclaimer.
