For those few women with allergy to the contrast material or impaired renal function, MRI could become a feasible study. The usefulness of an imagining technique that is not limited by the time constraints of contrast washout in performing biopsy, particularly multiple sites or both breasts, is ...
The CT scan protocol was performed using a 128 row MDCT scanner (Philips Ingenuity CT 128) with intravenous dynamic contrast medium injection. Abdominal MDCT was performed with the patient in the supine position, covering the area from the dome of the diaphragm to the inferior pelvic margin. In...
Magnetic resonance imaging contrast agents can enhance diagnostic precision but often face limitations such as short imaging windows, low tissue specificity, suboptimal contrast enhancement, or potential toxicity, which affect resolution and long-term monitoring. Here, we present a protein contrast agent ...
Ensures patient is prepared and radiologist-ordered protocols for pre-medications have been completed (e.g. contrast allergy pre-medication) Assesses patient’s need for care following contrast administration; arranges renal function tests and follow up according to radiologist protocol Provides education ...
MRI Protocol The MRI scan protocol included a UTE AC sequence, a 3D T1-weighted (T1W) MPRAGE both pre- and post-contrast injection with gadolinium, a T2-weighted (T2W) dark-fluid turbo inversion recovery magnitude (TIRM) (FLAIR) in both axial and coronal planes, a diffusion-weighted (DW...
Magnetic resonance imaging does not always require contrast agents in order to achieve a high degree of resolution. The literature indicates there is some increased risk of administering MRI contrast agents to patients with asthma or iodine allergy, but administration of these agents is still ...
Exclusion criteria were: previous knee replacement surgery, knee trauma in the preceding six months, absolute and relative contra-indications to undergo MRI; pregnancy, renal insufficiency (GFR < 60 mL/min/1.73m2) and known allergy to MR or US contrast agents. The institutional ethics review ...
The range of velocities resolved by our time-lapse MRI protocol was derived from simulations using synthetic phantoms that reproduced experimentally observed contrast. The simulations showed that contrast of moving cells was critically determined by the time cells remained within the dimensions of one vox...
