  1. MRI CASE Done By: Haya Al-ThuwainiRo’aa Al-Nemer Kholoud Al-Washmi Prepared For: Dr.Halima,,

  2. Out lines: The procedure: • Pt history • Clinical indication. • About the disease. • Scanner &sequences. • Finding & images.

  3. Procedure:MRI sellaturcica . • DOE:9-AUG-2010 • History: 33 years old female withheadache associated with blurred vision. • Clinical indication: R/O pituitary adenoma.

  4. Pituitary Adenoma Pituitary adenomas are a noncancerous growth in the pituitary gland. * account for about 15% of intracranial neoplasm's. TYPES of Pituitary Adenomas: They are classified based on size: • Pituitary microadenomas are smaller than 10 millimeters (more common). • Pituitary macroadenomas are 10 millimeters or larger.

  5. SYMPTOMS of Pituitary Adenomas: • Symptoms vary, depending on the size and location of the adenoma. • Tiredness, headaches, vision problems, vomiting, or dizziness. DIAGNOSES: • pituitary function testing (blood hormone levels) . • pituitary imaging: computed tomography (CT), MRI scan is preferred.

  6. TREATMENT for a pituitary adenomacan include: Depend on the type of tumor & its size: • Surgery • Radiation therapy. • Drug therapy.

  7. Scanner:GE (1.5 T) Sequence: FSE is: • a spin echo pulse sequence, but echo train length consists of several 180° rephasing pulses. • At each rephasing, an echo is produced and a different phase encoding step is performed.

  8. Fast Spin Echo advantages: • Short scan time. • Fast Spin Echo disadvantages: • higher SAR. • image blurring.

  9. TECHNIQE: Multiplaner, multisequential MRI as per pituitary protocol including the following sequence: • SAGITTAL T1 : TR = 650 , TE = minimum , echo train = 3 , BW = 15.6 , F = 320 , Q = 192 , NEX = 4 • SAGITTAL T1 FSE : The same as above. • CORONAL & AXIAL DIFFUSION : TR = 10000 , TE = min. , F = 128 , Q = 128 , NEX = 2 , P.value=1000 • CORONAL T2: TR = 2075 , TE = 120 , echo train = 17 , BW = 12 , F = 320 , Q = 224 , NEX = 4 • CORONAL T1 : TR = 450 , TE = min. , echo train = 2 , BW = 15 , F = 256 , Q = 224 , NEX = 4 • CORONAL T1 FSE : The same as above.

  10. Contrast media: • 4 ml half dose. • All sequences are taken pre + post CM except T2 sequence, it is only post CM. RF used coil: Head coil (volume coil).

  11. Findings: • The pituitary gland has normal size & signal intensity. • Homogeneous enhancement with no focal pituitary lesion or abnormal enhancement. Impression: Unremarkable MRI pituitary gland examination.
