The journal's publications cover all imaging modalities, radiology issues related to patients, policy and practice improvements, and clinically-oriented imaging physics and informatics. size in three dimensions. The goal of IMRT is to conform the radiation dose to the target and to avoid or reduce exposure of healthy tissue to limit the side effects of treatment. They are considered WHO grade 1 tumors in the current WHO classification of CNS tumors and correspondingly have a relatively good prognosis.. Radiology report. Pituitary adenoma can be described as microadenoma, macroadenoma, and giant tumors based on size. Cerebello-pontine angle.

Terminology. anterior pituitary ARVA, Augmented Radiology for Vascular Aneurysm, is a solution for automatic measurement of the maximum transverse diameter of the aorta. The journal is a valuable resource for practicing radiologists, radiologists-in-training and other clinicians with an interest in imaging. The differential diagnosis would include an astrocytoma and a meningioma. Hypophysectomy is the surgical removal of the hypophysis (pituitary gland). The pituitary is usually divided (in practice) into anterior and posterior parts, which actually refers to groupings of four subparts 4,5:. Although medulloblastoma has been classically thought of as a single entity, it is becoming increasingly evident that there are many distinct molecular and histological subgroups with overlapping clinical, histological and imaging features 8.. If the same tumor is greater than 10 mm in size, it is then considered a pituitary macroadenoma.Differences in presentation and Pituitary adenomas are tumors of the anterior pituitary. There is, however, a strong association with neurofibromatosis type 1 (NF1), particularly for the plexiform subtype.. Neurofibromas are generally divided into five morphological forms 1-8:. The pituitary gland sits atop the base of the skull in a concavity within the sphenoid bone called the sella turcica (pituitary fossa), immediately below the hypothalamus and optic chiasm..
