These tumors are based on their location within the uterine corpus as either submucosal, intramural, or subserosal(10). MRIs main advantages are its ability to depict tumor and provide great tissue contrast between the tumor and surrounding normal tissue. [10], When a muscle-splitting incision is made across gluteus maximus as part of the classical posterior approach and the muscle parted by hand-held or self-retaining retractors, the likelihood of damage to the inferior gluteal nerve is high. 8, Superior mesenteric vein. 5, Urinary bladder.

Ramage, J. Clearly "C" is already used for the cervical vertebrae. To address this issue, a physician may recommend a different contrast dye or administer an antihistamine (anti-allergy). The mass characteristically matures from the periphery to the center; a rim of calcification is seen by 6 to 8 weeks and is separate from the underlying bone. Thigh MRI Anatomy: T1-weighted axial view. The calcium will overlie the upper femoral shaft on an anteroposterior radiograph, and therefore may be best seen on a frog lateral radiograph or even more easily on axial CT images ( Figure 39-8 ). This webpage presents the anatomical structures found on hip MRI. MRI has high contrast resolution and tissue characterization capabilities that help characterize echogenic adnexal masses initially detected by ultrasound(17).

There are also a variety of clinical situations leading to local disturbances in the nerve function the positioning of the inferior gluteal nerve makes it vulnerable to iagtrogenic injury during posterior and posterior approaches to the hip[8], It is subject to injury by compression and ischemia in sedentary individuals, resulting in difficulty in rising from a sitting position and difficulty climbing stairs.
