What does it mean if a tumor is Hypervascular?

(HY-per-VAS-kyoo-ler) Having a large number of blood vessels.

What is Hypovascular metastasis?

Hypovascular liver metastases are predominantly supplied by portal venous branches, and demonstrate slower and less intense enhancement making them more conspicuous in portal venous phase images. Hence, MR imaging for liver metastases should include dynamic multiphase post-gadolinium SGE imaging.

What are the symptoms of brain metastases?

Common signs and symptoms of brain metastases include:

• Headaches.
• Seizures.
• Weakness in the arms or legs.
• Loss of balance.
• Memory loss.
• Speech disturbance/problems talking.

What does Hyperenhancement mean?

Noun. hyperenhancement (countable and uncountable, plural hyperenhancements) Greater than normal enhancement. (radiology) Greater than background-level brightness.

What does non Hypervascular mean?

Non-hypervascular HBPI hypointense nodules were defined as solid nodules with low signal intensity on HBPI, while not showing higher signal intensity than that of the spleen on heavily T2WI. 18.

How long can you live with metastatic brain tumors?

A decade and a half ago, people diagnosed with a brain metastasis survived, on average, less than 6 months. Treatments have improved in the intervening years, and today, people with brain metastases are living longer than ever before.

What does enhances homogeneously mean?

a Homogeneous enhancement is defined as a uniform attenuation of a tumor on post-contrast images; b, c heterogeneous enhancement is defined as a mixture of high and low attenuation within a tumor on post-contrast images; heterogeneous enhancement < 50% of tumor area (Fig.

What does Hyperenhancement mean on MRI?

Arterial hyperenhancement was defined as a hyperdense or hyperintense lesion unequivocally greater than the surrounding liver according to the current guidelines (1,2). Next, unenhanced images with arterial phase images were reviewed to identify absolute arterial enhancement.

What is mucosal Hyperenhancement?

Mucosal hyper-enhancement was defined radiologically as segmental hyperattenuation of the bowel wall (when absent mural stratification) compared with other normal loops or of enhanced inner aspect (mucosa) of the bowel wall (when present mural stratification).

What is washout on MRI?

Washout appearance is defined as a visually assessed temporal reduction in enhancement relative to surrounding liver from an earlier to a later phase, resulting in portal venous or delayed phase hypoenhancement (12).

How fast do metastatic brain tumors grow?

This study demonstrated the mean interval from primary lung cancer diagnosis to brain metastasis was 1.17 years and 4.64 years in the breast cancer group. This is slightly longer than the average time of diagnosis of breast cancer to brain metastasis previously reported of 34 months (2.83 years).

Is gadolinium the same as Eovist?

Eovist is a prescription medicine called a gadolinium-based contrast agent (GBCA). Eovist, like other GBCAS, is injected into your vein and used with a magnetic resonance imaging (MRI) scanner. An MRI exam with a GBCA, including Eovist, helps your doctor to see problems better than an MRI exam without a GBCA.

What does homogeneously mean?

1 : of the same or a similar kind or nature. 2 : of uniform structure or composition throughout a culturally homogeneous neighborhood.

What is homogeneously enhancing mass?

Homogeneous enhancement Homogeneous enhancement is uniform and confluent enhancement throughout the mass. The homogeneous enhancement often is suggestive of benign lesion. However, spatial resolution may limit observations on small foci.

What does arterial Hyperenhancement mean?

Arterial phase hyperenhancement, sometimes termed arterial “wash-in” or arterial “hypervascularity,” is defined as enhancement in the arterial phase that unequivocally is greater than that of surrounding liver.

What is shock bowel?

Shock bowel has been described as CT ev- idence of a diffusely abnormal appearance of the bowel in patients who are hypovolemic after trauma [1–3]. The bowel has been char- acterized as abnormally intensely enhancing, fluid filled, and thick walled.

What is a washout of lesion?

Washout. The term rapid washout is presence of hypodensity or hypointensity of the lesion as compared to rest of the liver on portovenous or delayed phases, and has a specificity of 95–96% for diagnosis of HCC.
