MDCalc was founded by two emergency physicians, Graham Walker, MD, and Joseph Habboushe, MD, MBA, [5] and provides over 500 medical calculators and other clinical decision-support tools. [6] The MDCalc.com website was launched in 2005. [5] In 2016, MDCalc launched an iOS app, [7] followed by an Android app in 2017. [8]
Adrenal-dedicated CT and MRI imaging can be performed to distinguish benign adenomas from potentially malignant lesions. [12] [13] Online calculators assist radiologists in calculating the washout of contrast in adrenal nodules on CT [14] and chemical shift on MRI. [15] Hormonal evaluation can also be helpful, which includes: [11]
MRI is the most sensitive and specific method for adrenal hemorrhage diagnosis. [18] On MRI, haemorrhages could appear as different signals in the acute, subacute and chronic stages, which facilitates the surveillance of adrenal hemorrhage aging.
Adrenal insufficiency is a condition in which the adrenal glands do not produce adequate amounts of steroid hormones.The adrenal glands—also referred to as the adrenal cortex—normally secrete glucocorticoids (primarily cortisol), mineralocorticoids (primarily aldosterone), and androgens.
An adrenocortical adenoma or adrenal adenoma is commonly described as a benign neoplasm emerging from the cells that comprise the adrenal cortex. Like most adenomas , the adrenocortical adenoma is considered a benign tumor since the majority of them are non-functioning and asymptomatic .
There, the doctors scanned through my MRI and said the mass looked benign, but they offered to take it out since it was causing me so much pain. Yes, please. I had the surgery the following week ...
Magnetic resonance elastography (MRE) is a form of elastography that specifically leverages MRI to quantify and subsequently map the mechanical properties (elasticity or stiffness) of soft tissue. First developed and described at Mayo Clinic by Muthupillai et al. in 1995, MRE has emerged as a powerful, non-invasive diagnostic tool, namely as an ...
Diffusion imaging is an MRI method that produces in vivo magnetic resonance images of biological tissues sensitized with the local characteristics of molecular diffusion, generally water (but other moieties can also be investigated using MR spectroscopic approaches). [15] MRI can be made sensitive to the motion of molecules.
