Evaluation of known endometriosis with MRI requires a slightly different protocol to a routine pelvic MRI (see pelvic MRI protocol: routine) and should probably be reserved for known cases of endometriosis rather than for the assessment of pelvic pain. IV or IM Buscopan is administered to reduc...

Examination of the liver with MRI requires numerous sequences and imaging at multiple times after the administration of contrast.   Note: This article is intended to outline some general principles of protocol design. The specifics will vary depending on MRI hardware and software, radiologist's...

MRI protocol for anal canal cancer is a group of MRI sequences put together to asses extension and stage anal canal tumors. Note: This article is intended to outline some general principles of protocol design. The specifics will vary depending on MRI hardware and software, radiologist's and ref...

MRI protocol for the assessment of perianal fistulas is a group of MRI sequences put together to asses the extension and anatomic relationships of inflammatory fistulas to the anal sphincters, helping to plan surgical management and monitor treatment response.  NB: This article is intended to o...

MRI protocol for rectal cancer is a group of MRI sequences put together for imaging staging of primary tumors of the rectum and assessment of response following neoadjuvant therapy. Modified versions of the protocol may also be used for the assessment of local recurrence. Note: This article is ...

The brain MRI stereotactic study, also known as frame-based stereotactic MRI study or conventional brain MRI stereotaxis, is a localization MRI protocol that delineates an intracranial structure or lesion in relation to a three-dimension coordinate system allowing precise surgical access to them...

Brain screen protocol is a simple non-contrast MRI protocol comprising a group of basic MRI sequences as a useful approach when imaging the brain when no particular condition is being sought (e.g. headache). The protocol is designed to obtain a good general overview of the brain. Additionally, t...

MRI protocol for brain tumor assessment is a group of MRI sequences put together to best approach CNS tumors in general. Note: This article is intended to outline some general principles of protocol design. The specifics will vary depending on MRI hardware and software, radiologist's and referr...

MRI protocol for stroke assessment is a group of MRI sequences put together to best approach brain ischemia. CT is still the choice as the first imaging modality in acute stroke institutional protocols, not only because the availability and the easy and fast access to a CT scanner, but also due...

MRI protocol for brain infection assessment is a group of MRI sequences put together to best approach CNS infections in general. Note: This article is intended to outline some general principles of protocol design. The specifics will vary depending on MRI hardware and software, radiologist's an...

MRI protocol for brain trauma is a group of MRI sequences put together to best approach traumatic brain injury, especially diffuse axonal injury.  Note: This article is intended to outline some general principles of protocol design. The specifics will vary depending on MRI hardware and software...

MRI protocol for demyelinating diseases is a group of MRI sequences put together to best approach these white matter disorders characterized by the destruction or damage of normally myelinated structures. These disorders may be inflammatory, infective, ischemic or toxic in origin.  Historically...

MRI protocol for epilepsy is a set of MRI sequences aimed at improving sensitivity and specificity in identifying possible structural abnormalities that underlie epilepsy (e.g. mesial temporal sclerosis and malformation of cortical development).  Perhaps more than most other MRI protocols, stud...

MRI protocol for a quick stroke assessment corresponds to a short protocol, usually just the DWI/ADC, adopted by some institutions as a complementary tool to the CT imaging in stroke code patients. The aim is to provide additional information to support stroke diagnosis within the narrow time wi...

MRI protocol for the pineal and tectal plate assessment is a group of MRI sequences put together to best approach tumors involving this region.  The pineal region is best imaged with MRI although CT, angiography, and ultrasound (in infants) also play a role. Please refer to the article pineal r...

The MRI sacroiliac joint protocol encompasses a set of MRI sequences for the routine assessment of sacroiliac joints. Note: This article aims to frame a general concept of an MRI protocol for the assessment of the sacroiliac joint. Protocol specifics will vary depending on MRI scanner type, spe...

Zero echo time (ZTE) imaging is a relatively recent development in MR technology, with the aim to better visualize tissues such as bone with the shortest T2 values.  Physics In ZTE, the signal is acquired immediately after applying the radiofrequency pulse resulting in near-zero echo times. Af...
