What does red on an ultrasound mean?

On a Doppler ultrasound, red signifies blood flowing toward the ultrasound probe (transducer), representing arterial flow, while blue indicates flow away from it, usually venous flow; brighter shades mean faster flow, helping diagnose circulation issues by showing vessel health, blockage, or abnormal patterns, though the colors themselves aren't inherently good or bad, just directional.

Why did my ultrasound show red?

In a color Doppler ultrasound, red generally shows blood flowing toward the ultrasound probe, while blue shows blood flowing away from it. This color mapping helps healthcare professionals evaluate blood flow in vessels, identifying any blockages or abnormal blood flow patterns.

What color is a tumour on ultrasound?

Grey represents hypoechoic structures such as solid-mass dense tissues (e.g., fibroids, tumours, and lymph nodes) that give fewer echoes than surrounding tissues. Varying grey shades indicate different densities.

What color is a cyst on an ultrasound?

Like follicles, cysts usually appear round and black on an ultrasound. They often have thin walls and don't look like they contain anything inside. However, they are often larger than normal follicles. Cysts don't usually need any treatment and are often not a cause for concern.

What do the colors on an ultrasound represent?

On an ultrasound, colors primarily show blood flow direction and speed in Color Doppler mode: red usually means flow toward the probe, blue means flow away, and brighter shades indicate faster speed. In grayscale, white is dense tissue/bone, gray is softer tissue, and black often signals fluid, while colors like yellow/orange/green can show turbulent flow or be part of custom "maps" to highlight specific flow patterns, but don't inherently mean disease like cancer.

What would a cancerous lump look like on ultrasound?

A cancerous lump on an ultrasound often looks like a dark (hypoechoic), irregularly shaped mass with jagged, unclear, or "scribbled" edges (spiculated), sometimes appearing taller than it is wide, blocking sound waves (posterior shadowing), and potentially showing increased blood flow, contrasting with smoother, well-defined benign lumps. However, not all suspicious-looking lumps are cancer, and some cancers can appear benign, so a biopsy is needed for a definitive diagnosis, note this YouTube video's transcription, Scan.com UK and this article from Everhope Oncology.
 

Can an ultrasound tell if it's a cyst or tumor?

Yes, an ultrasound is a primary tool for telling the difference: cysts look like dark, fluid-filled sacs with smooth walls, while tumors appear as solid, denser masses that reflect sound differently, but complex growths need further tests like biopsy or MRI for definitive diagnosis. Radiologists use the echo patterns and internal features to classify lumps, but if a mass is complex (mixed solid/fluid), more investigation is needed to check for cancer.
 

What does a cancerous ovarian cyst look like on an ultrasound?

A cancerous ovarian cyst often looks like a large, complex mass with thick, irregular walls and internal divisions (septations), solid-appearing nodules or papillary growths, and increased, chaotic blood flow (vascularity) on a Doppler ultrasound, unlike simple benign cysts that are usually just fluid-filled with thin walls and regular flow. These "suspicious" features, including solid components and abnormal blood supply, raise concern for malignancy, requiring further testing like MRI or blood tests (like CA-125) for a definitive diagnosis, as ultrasound alone isn't definitive.
 

Can ultrasound detect inflammation?

Yes, ultrasound is a powerful tool for detecting inflammation in joints, tendons, ligaments, and soft tissues, allowing for early diagnosis, monitoring disease progression, and guiding treatment, often showing fluid buildup, swelling, or increased blood flow (using Doppler) that signals active inflammation, even when it's not obvious clinically.
 

What color is a benign tumour?

Dermatofibroma are considered to be a benign tumour, or may represent a fibrous reaction to minor trauma and insect bites. They are firm raised papules or nodules. They vary in colour from brown to purple and red. They occur anywhere but are seen most commonly on the lower limb.

What does PCOS look like on an ultrasound?

On an ultrasound, PCOS often looks like ovaries with many small, undeveloped follicles (immature eggs) lining the edge in a "string of pearls" pattern, alongside increased ovarian size and denser tissue, indicating hormonal issues preventing normal ovulation. A normal ovary shows a few follicles, with one dominant one maturing, but PCOS ovaries lack this dominant follicle and show multiple small ones (2-9mm) clustered peripherally.
 

What is concerning on a pelvic ultrasound?

Abnormalities in the anatomic structure of the uterus, including endometrial conditions. Fibroid tumors (benign growths), masses, cysts, and other types of tumors within the pelvis. Presence and position of an intrauterine contraceptive device (IUD)

What follow-up is needed after an ultrasound?

After discussing the findings with your healthcare provider, they may recommend follow-up imaging, biopsies, or specialist consultations. This can include additional ultrasounds, MRI, or CT scans for more detail.

How can I check my ultrasound report?

To check an ultrasound report, focus on the Findings (what was seen) and Impression/Conclusion (radiologist's summary) sections, looking for measurements, descriptions of organs (black=fluid, gray=tissue, white=dense/bone), and any abnormal observations like nodules or fluid issues, but always discuss it with your doctor as they interpret it for your specific health context. 

What does red color on ultrasound mean?

On a Doppler ultrasound, red signifies blood flowing toward the ultrasound probe (transducer), representing arterial flow, while blue indicates flow away from it, usually venous flow; brighter shades mean faster flow, helping diagnose circulation issues by showing vessel health, blockage, or abnormal patterns, though the colors themselves aren't inherently good or bad, just directional.
 

Can you tell if something is cancerous from an ultrasound?

Yes, ultrasound can help detect cancer by visualizing tumors and abnormalities in soft tissues (like breast, liver, thyroid), differentiating solid masses from cysts, and guiding biopsies, but it cannot definitively diagnose cancer alone; a biopsy is needed for confirmation, as it can't always distinguish benign from malignant growths. It's a safe, non-invasive tool, often used with other imaging (like mammograms) for clearer pictures or when radiation is a concern, but it has limitations in certain areas like lungs or bones. 

What are the signs that a cyst is cancerous?

You can't definitively know if a cyst is cancerous just by looking; the only way to confirm is through medical evaluation, but suspicious signs on imaging (like solid parts, irregular walls, "dirty" fluid) or changes in a lump (rapid growth, pain, bleeding, color change) warrant a doctor visit, potentially leading to a biopsy, which is the gold standard for diagnosis. Most cysts are benign (non-cancerous), but a doctor uses imaging (ultrasound, CT, MRI) and possibly fluid/tissue samples (biopsy) to tell the difference.
 

What are the signs that you have a cancerous lymph node?

Lymph node cancer (lymphoma) often starts with painless swelling in the neck, armpits, or groin, accompanied by "B symptoms" like persistent fever, drenching night sweats, and unexplained weight loss, along with deep fatigue, itching, or abdominal issues. While these symptoms warrant a doctor's visit, they can also signal other conditions, so a biopsy is crucial for diagnosis.
 

Can ultrasound tell if a cyst is cancerous?

An ultrasound can strongly suggest if a cyst is benign (simple, fluid-filled) or potentially concerning (complex with solid parts, debris, or abnormal blood flow), but only a biopsy (tissue sample) can definitively diagnose cancer, as ultrasounds can't confirm malignancy, only flag suspicious features for further testing like MRI, aspiration, or surgery. Simple cysts look clear and dark on ultrasound, while complex ones need more investigation. 

What does a cyst look like on ultrasound?

On ultrasound, a simple cyst typically looks like a dark (anechoic), round or oval, well-defined sac with smooth, thin walls, appearing as a clear fluid-filled structure that shows bright echoes behind it (posterior acoustic enhancement). Complex cysts, however, can have internal echoes, thick walls, solid components, or septations (partitions), suggesting blood, tissue, or debris, and may need further investigation.
 

What do the colors indicate on an ultrasound?

On an ultrasound, colors primarily show blood flow direction and speed in Color Doppler mode: red usually means flow toward the probe, blue means flow away, and brighter shades indicate faster speed. In grayscale, white is dense tissue/bone, gray is softer tissue, and black often signals fluid, while colors like yellow/orange/green can show turbulent flow or be part of custom "maps" to highlight specific flow patterns, but don't inherently mean disease like cancer.
 

What is the red circle on an ultrasound?

What does red or blue mean on an ultrasound? Red and blue colors represent the movement of the blood. Blue represents blood flow away from the probe, while red represents the blood flowing towards the probe.

What is the red shading on an ultrasound?

For example, blue may indicate blood flowing away from the transducer (towards negative Doppler shifts), while red represents blood moving towards the transducer (positive Doppler shifts). By evaluating these colors and grayscale imaging, clinicians can assess vascular conditions such as stenosis or thrombosis.
