ROUB study guide
ROUB · Work through your exam, one topic at a time.
ROUB is the exam code this page is being built around, and the source retrieved for it does not describe the credential. The link that should define it, ardms.org/get-certified/credentials/roub/, redirects to a 404 page on inteleos.org reading "This page is off the map," so no official statement of scope, eligibility, format, length, fee, or pass score is available here. What the retrieved page does confirm is the surrounding landscape: Inteleos is the parent organization, ARDMS credentials are listed as RDCS, RDMS, RMSKS and RVT, APCA credentials include RMSK and RPVI, and the POCUS Certification Academy sits under Inteleos certifications. The site also groups its exams into four areas of practice: General Sonography and Maternal Fetal Health, Musculoskeletal Health, Point of Care Ultrasound, and Cardiovascular Health. Topics on this exam: General Sonography and Maternal Fetal Health, Musculoskeletal Health, Point of Care Ultrasound, and Cardiovascular Health. The ROUB study guide has 4 sections and about 1,166 words.
01General Sonography and Maternal Fetal Health
This domain tests image optimization, safety, and obstetric measurement: dating, biometry, amniotic fluid, and umbilical artery Doppler. ALARA: use the lowest output that yields diagnostic images. Monitor thermal index (TIB when bone is in the beam) and mechanical index; limit dwell time, especially in the first trimester and with Doppler. Match probe and preset to depth.
332 words, about 2 min02Musculoskeletal Health
This domain tests tendon, ligament, muscle, and joint ultrasound: probe orientation, anisotropy, dynamic maneuvers, and Doppler for inflammation. Tendons are fibrillar and echogenic when the beam is perpendicular. Anisotropy occurs when the beam is not at 90°; the tendon becomes falsely hypoechoic and mimics a tear. Scan in two orthogonal planes and confirm with dynamic movement or contralateral comparison.
282 words, about 1 min03Point of Care Ultrasound
This domain tests focused, goal-directed bedside scanning: lung, FAST, vascular, and basic cardiac views. It rewards a clear clinical question, standard windows, and artifact recognition. Lung: identify the pleural line and sliding with A-lines. B-lines are vertical, laser-like, arise from the pleura, and move with respiration.
272 words, about 1 min04Cardiovascular Health
This domain tests basic echocardiography and vascular screening: chamber size, LV systolic function, valves, aorta, and carotid. Parasternal long axis: RV anterior, LV posterior, aortic root, left atrium. Measure the aortic root at the sinuses of Valsalva; measure LV dimensions at the chordal level, perpendicular to the long axis. Avoid foreshortening: the LV apex should be a true apex, not a rounded truncation, and the aortic and mitral valves should align.
