6 Best Free Online Adrenal Washout Calculator Websites
Here is a list of best free online adrenal washout calculator websites. During a CT scan, a dye is injected into the bloodstream of a patient to highlight different tissues and structures. When an adrenal mass loses its brightness filled with dye during a CT scan is referred to as adrenal washout. Adrenal washout helps doctors differentiate between benign adrenal adenomas and malignant lesions. Adrenal washout is calculated using the density of adrenal mass on three different CT scans. The first CT scan is known as Non-Enhanced Scan (it is taken before any dye injection). The second scan (Portal Venous Phase scan) is performed after 60 to 75 seconds after the contrast (dye) injection. This final scan (Delayed Scan) is taken after 15 minutes of contrast injection. If you want to calculate the adrenal washout, check out these online adrenal washout calculator websites.
Using these websites, users can quickly calculate adrenal washout. To do that, users need to enter the density of adrenal masses on all three CT scans (Non-enhanced scan, Portal venous phase scan, and Delayed scan). After the calculation, users get Absolute Washout and Relative Washout values in percentage indicating the adrenal washout rate. Most of these websites also describe the meaning of obtained values like an absolute washout of more than 60 percent or higher indicating adenoma. These websites also show the adrenal washout calculation formulas with examples. To help new users, I have included the necessary calculation steps in the description of each website. Go through the list to learn more about these websites.

Frequently Asked Questions
During a CT scan, a dye is injected into the bloodstream of a patient to highlight different tissues and structures. When an adrenal mass loses its brightness filled with dye during a CT scan is referred to as adrenal washout.
The Relative Percentage Washout (RPW) is a measure of the contrast washout from the adrenal gland over time and is commonly used in the evaluation of adrenal lesions to help differentiate between benign and malignant masses. The calculation involves measuring the attenuation (density on CT) or signal intensity (on MRI) of the adrenal lesion at different time points during the contrast enhancement phases.
In radiology, "washout" refers to the reduction or decrease in contrast enhancement within a lesion or tissue over time during dynamic imaging studies. This term is commonly used in the context of contrast-enhanced imaging techniques such as computed tomography (CT) or magnetic resonance imaging (MRI).
The contrast washout characteristics of adrenocortical carcinoma (ACC) can vary, and there is no one-size-fits-all pattern that definitively distinguishes ACC from benign adrenal lesions. However, in general, adrenocortical carcinomas tend to demonstrate less washout of contrast compared to benign adrenal adenomas.
Relative washout is a term used in radiology to describe the decrease in contrast enhancement of a lesion or tissue relative to the surrounding normal tissue. It is often expressed as a percentage and is calculated using measurements of contrast density or signal intensity on imaging studies, such as computed tomography (CT) or magnetic resonance imaging (MRI).
