Radiofrequency ablation
Hepatocellular carcinoma is one of the most common malignant tumours in Egypt and worldwide. Surgical resection remains the gold standard of hepatic malignancy; however few patients are ideal candidates for surgical resection because of technical difficulties, age at the time of diagnosis, and advanced cirrhosis. For these reasons, multiple other therapies have been shown to be used, especially ethanol injection, trans-arterial chemo-embolization and recently Radiofrequency ablation therapy. Radiofrequency ablation has become an important therapeutic option for HCC. It is effective, safe, and relatively straightforward and results in better local control of small HCC (less than 5 cm) than either percutaneous ethanol instillation or trans-arterial chemo-embolization.

Specialized OB/GYN ultrasound Unit
Runed by very specialized team under supervision of the expert professor used to deal with.The unit is equipped with advanced ultrasound machines with 3D capability and ultrasound guided interventional set, a foetal cardiography unit (C.T.G.) and video recording.List of available studies:

	Gynecological pelvic study.
	Folliculometry.
	Duplex Doppler and color flow imaging for gynecological problems.
	Detailed obstetric scan.
	Duplex Doppler and color flow imaging for obstetrics.
	Fetal well being including biophysical profile, CTG and Doppler.
	3D study for obstetrics and gynecology.
	Amniocentesis whether diagnostic or therapeutic.
	Cyst aspiration.
	Fetal decompression.
	Guided biopsy.
	Ultrasound guided obstetrics and gynecology interventions.

Ultrasound continues to make important and significant contributes to patient enhancing their quality of life; and volume acquisition by 3D technique is even enhancing its ability more and more; and that is why we announce the start of our 3D unit at Misr Radiology Center with the following available services and techniques:

	Surface rendering.
	Volume rendering.
	Multiplanar reformation.
	Panoramic extended study.
	Opacity, transparency and bone X-ray views.

These 3D techniques can be used in different parts of the body life:

	Obstetrics.
	Gynecology.
	Genitourinary e.g. kidney and bladder.
	Abdomen e.g. liver masses and vascular flow.
	Small parts e.g. testis and blood flow.
	Breast.
	Vascular system.

MR spectroscopy

	MR proton spectroscopy is the study of specific resonance frequencies of certain molecules present in a tissue to assess its disease state. It achieves non-invasive tissue characterization through detecting the presence of certain brain metabolites and determining their changing concentrations, which correlates with pathologic processes.
	MRS provides additional information to routine MRI by evaluating the metabolic data in brain neoplasm that may precede structural abnormality.
	MRS has no specific contraindications other than those of MRI and could be added to conventional MRI studies.

MR angiographic application (Bolus track technique).

MRI: New state of the art

4-Diffusion with ADC map:

To detect hyperacute and acute ischemic/infractions.

To diagnose, better characterize and follow-up brain tumors, MS and brain infections.

Acute right basal ganglia/internal capsule infarction which is only seen on the diffusion weighted sequence and not seen on T2 sequence (a new technique for detection of infarction)

5-Post contrast perfusion maps and curves:
	To analyze the perfusion date of hyperacute infarctions (before 6 hours) in order to properly select conditions for thrombolytic therapy via rTPA (recombinant tissue plasminogen activator).
	To follow-up therapy of malignant brain tumors.
	To distinguish tumors from infarcts.

	Perfusion MRI showing left middle cerebral artery territory occlusion

6-Post contrast magnetization transfer (MT) studies and magnetization transfer ratio (MTR):
	To best detect brain metastasis and MS plaques.
	To best evaluate and follow-up MS cases.

7-MR Cerebro-spinal flow (C.S.F.) flow studies:

	To study hydrocephalus and atrophy quantitatively.
	To differentiate neural pressure hydrocephalus from atrophy and from obstructive hydrocephalus.
	To follow-up shunt tubes functions quantitatively.

8-MR neurography:
	To study injuries of individual nerves as radial, sciatic, popliteal nerves, etc.
	To evaluate brachial and sacral plexuses.

9-Post contrast enhanced MR angiography of carotids & vertebral arteries:
	To actually study extra-cranial carotid and vertebral arteries for any stenosis or occlusion after the I.V. injection of Gd-DTPA using an MR pump injector so as to evaluate these vessels in a way similar to conventional catheter angiography. N.B.: The same examination is performed for abdominal vessels e.g. renal, hepatic, portal, superior mesenteric and also for the peripheral vessels of the limbs.
