What is a hypodense lesion in the spleen?
• Most hypodense splenic lesions on CT represent benign lesions that require no further work-up. • For correct interpretation, hypodense splenic lesions need to be evaluated in the clinical context.
What is hypodense lesion in liver?
Most liver metastases are hypovascular and as a result are hypodense on CT in comparison with normal liver parenchyma during the portal venous phase (PVP). Colon, lung, breast, and gastric cancers are the most common causes of hypovascular liver metastases.
What does hypodense lesion mean?
Hypodense (less dense): If an abnormality is less dense than the reference structure, we would describe it as hypodense.
What is multiple Hypodense?
Multiple hyperdense or hypodense lesions are visible in both kidneys on native or contrast-enhanced CT-scans. Fig. 3. Histology of the renal biopsy showing dense infiltration of the kidney with the known malignant lymphoma.
What causes Hypodensity in spleen?
Haemangiomas, congenital in origin, represent the most common benign lesions of the spleen. Lymphoma represents the most common malignant tumour of the, usually secondarily involved, spleen. Most hypodense splenic lesions on CT represent benign lesions that require no further work-up.
What does Hypodense mean on CT?
The appearance of tissues on a CT scan is described in terms of ‘density’. Darker structures are ‘hypodense or low density’; brighter structures are ‘hyperdense or high density’. Blood Can Be Very Bad is a mnemonic that can be used when faced with interpreting a CT head scan: Blood. Cisterns.
Are liver cysts Hypodense?
In autosomal polycystic liver disease, the numerous hepatic cysts of various sizes have features identical to those described for benign developmental hepatic cysts—well-circum- scribed round lesions that are hypodense and nonenhancing at CT; hypointense on T1-weight- ed imaging, hyperintense on T2-weighted imaging ( …
Should I worry about liver lesions?
Liver lesions are abnormal growths that may be noncancerous (benign) or cancerous. Benign lesions occur for a variety of reasons and are typically not cause for concern.
What does Hypodense mean in MRI?
Hypodense – darker areas. Grey/Isodense – intermediate density similar to brain tissue.
What is difference between Hypodense and Hyperdense?
The appearance of tissues on a CT scan is described in terms of ‘density’. Darker structures are ‘hypodense or low density’; brighter structures are ‘hyperdense or high density’.
