Students: What general procedure is this? How would you describe the guidance approach? Residents: If this pt presented with a humerus fracture, what specific procedure is this called? #raysofgray #POCUS #ultrasound #FOAMed #MedEd #emergencymedicine #medicalstudent #resident

RESOLUTION S: Left kidney and spleen are shown. R: There is a hyperechoic well circumscribed lipoma that is incidentally noted.  No hydronephrosis or other masses.

RESOLUTION S: This is a testicle with power Doppler applied to assess for torsion. R: Blood flow is present, as well as a small hydrocele and microlithiasis (incidental finding)

RESOLUTION S: This is a needle viewed in-plane (hyperechoic with posterior reverberation artifact) within a hypoechoic soft tissue abscess. R: Ultrasound-guided abscess aspiration.

RESOLUTION: S: The convex transducer is on the abdomen R: There is “hot” (inflamed) fat surrounding a transverse cut of bowel that is under 2cm with a thickened wall. Ddx includes diverticulitis and appendicitis.

@lignosmihail Good ddx!

RESOLUTION S: A nerve block is being performed, where a halo of anesthetic is injected around the nerve of interest. R: Posterior tibial nerve block.

RESOLUTION S: The linear transducer is positioned over the proximal left leg. R: Deep venous thrombosis (DVT) in the common femoral vein (CFV).

RESOLUTION S: A convex (curvilinear) transducer on the abdomen (likely just above the umbilicus) R: Abdominal Aortic Aneurysm (AAA)

RESOLUTION S: Flexor surface of a finger in a water bath showing dermis, pulp, tendon and bone. R: There is a distal phalanx fracture.

RESOLUTION S: Sagittal view through the uterus and bladder. R: Fibroids make the uterus look enlarged and heterogenous.
