Should I be worried about liver lesions?
Also referred to as a liver mass or tumor, liver lesions can be either benign (noncancerous) or malignant (cancerous).
Benign liver lesions are very common and are generally not a cause for concern.
Malignant liver lesions, however, require intervention and treatment..
What does hyperechoic pancreas mean?
Hyperechoic pancreas was defined as a homogeneous echogenicity of the pancreatic body that was slightly lower than or equal to the echogenicity of retroperitoneal fat.
Can a hypoechoic nodule be benign?
Spongiform nodules, purely or predominantly cystic nodules, nodules with well-defined hypoechoic halo and echogenic as well as isoechoic nodules are usually benign. None of the US characteristics have 100% accuracy in detecting or excluding malignancy.
What is hyperechoic on ultrasound?
Hyperechoic – A relative term that refers to the echoes returning from a structure. Hyperechoic tissues generate a greater echo usually displaying as lighter colors during ultrasound imaging. Hypoechoic – Refers to structures that create weaker echoes such as a fluid.
What does Black on ultrasound mean?
If you remember that FLUID is always BLACK and TISSUE is GRAY. The denser the tissue, is the brighter white it will appear in ultrasound the brightest white being bone.
What appears black on ultrasound?
Liquids, such as water or urine, transmit sound waves readily. Therefore, a structure filled with urine or water appears black or dark gray on the ultrasound monitor.
What percentage of hypoechoic breast nodules are malignant?
Irregular hypoechoic breast masses on US are usually considered suspicious BI-RADS category 4, but BI-RADS category 4 lesions are known to have a broad range of malignant rates (3-94%), and these lesions on US vary significantly on histopathological examinations.
What is meant by hyperechoic?
Ultrasound is a very good tool to direct the diagnostic pathway. Ultrasound terms: Hyperechoic – more echogenic (brighter) than normal. Hypoechoic – less echogenic (darker) than normal. Isoechoic – the same echogenicity as another tissue.
Is hyperechoic black or white?
Based on echogenicity, a structure can be characterized as hyperechoic (white on the screen), hypoechoic (gray on the screen) and anechoic (black on the screen) [Figure 1].
Is hypoechoic or hyperechoic better?
Hypoechoic: Gives off fewer echoes; they are darker than surrounding structures. Examples include lymph nodes and tumors. Hyperechoic: Increased density of sound waves compared to surrounding structures. Examples include bone and fat calcifications.
What does hyperechoic lesion mean?
According to the BI-RADS lexicon , a hyperechoic lesion is defined by an echogenicity greater than that of subcutaneous fat or equal to that of fibroglandular parenchyma. Only 1–6% of breast masses are hyperechoic and the great majority of them are benign.
Are cysts hypoechoic or hyperechoic?
Cysts are generally black or echo-free in an ultrasound image, while solid tumours have a range of densities leading to a range of echos, from hypoechoic, to isoechoic, to hyperechoic. Cysts have typically features, which are explained in the following text.
