An ultrasound of the calf, a venous duplex and Doppler scan, visualizes calf veins, arteries and surrounding soft tissues. It shows blood flow, vessel compressibility and valve function, detecting deep vein thrombosis, partial or complete clots, venous insufficiency and arterial flow problems. It can also identify muscle or tendon injury, hematoma, cysts or fluid collections and guide treatment decisions.

Your right calf is the back portion of your lower right leg between the knee and the ankle. It contains the calf muscles—gastrocnemius and soleus—sitting over the tibia and fibula and connected to the heel via the Achilles tendon. The calf helps point the foot (plantarflexion), supports standing, walking and balance, and can ache after exertion or injury.

A calf scan is a non‑invasive ultrasound (Doppler/duplex) exam of the calf veins to detect deep vein thrombosis (blood clots) or assess blood flow. A handheld probe plus compression maneuvers visualise veins and any clot or impaired flow. It’s used when you have calf pain, swelling, redness, warmth, or a raised D‑dimer to guide diagnosis and treatment.

Yes — ultrasound commonly detects calf muscle tears by showing disruption of muscle fibers, fluid or hematoma, and retraction, and can estimate size and location. It’s fast, cost‑effective and allows dynamic comparison, but accuracy depends on operator skill and timing. Small, deep or complex injuries may be missed, in which case MRI is more sensitive for full assessment.

Yes. Ultrasound can detect many soft‑tissue masses in the leg, distinguishing cystic versus solid lesions, estimating size and location, and assessing blood flow with Doppler. It’s limited for deep, intra‑muscular or bone‑related tumors and can’t fully characterize malignancy; MRI is superior for extent and staging. Ultrasound also helps guide biopsies. See a physician for appropriate imaging.

When to worry about calf pain: seek urgent care for sudden severe calf pain, marked swelling, warmth, redness, a hard tender cord, or inability to bear weight—these may signal deep vein thrombosis or muscle rupture. Also get immediate help for breathlessness, chest pain, fainting, high fever, or after recent surgery/immobility. See your doctor promptly for persistent, worsening, or unexplained calf pain.
