   c.       Emphysema
   d.      Pulmonary oedema
   e.      Bronchiolitis
   2.       In renal imaging, which of the following is incorrect?
   a.       Small sized kidneys are seen in chronic kidney disease
   b.      A discrepancy in kidney size greater than 2cm may suggest unilateral renal artery stenosis
   c.       In the assessment of renal size, intravenous urography is more accurate than ultrasound
   d.      Intravenous urography is problematic in the elderly
   e.      It is of use in diagnosing obstructive uropathy
   3.       The usual trauma series of radiographs  include the following except
   a.       Lateral cervical spine X-ray
   b.      An antero-posterior chest X-ray
   c.       An antero-posterior pelvic X-ray
   d.      All of the above
   e.      None of the above
   4.       Which of the following is an incorrect about radiological investigation of diseases of the brain?
   a.       Computed tomography is a technique of choice for investigating brain lesions
   b.      Magnetic Resonance Imaging has limited use
   c.       Positron-Emission Tomography is useful in certain aspect of brain disease by showing differences in local brain metabolism
   d.      Ultrasound is very useful in neonates because they have window of an open fontanelle.
   e.      Simple radiography of the skull is still valuable in assessment of skull trauma
   5.       The usual contrast enhancement media used during  magnetic resonance imaging of brain lesions is:
   a.       Gastrographin
   b.      Xenon
   c.       Iodine
   d.      Gadolinium
   e.      Barium
   6.       Which of the following is incorrect about CT-cisternography?
   a.       There is enhanced contrast between the cerebrospinal fluid and neural tissue
   b.      It requires the intrathecal injection of a water soluble myelographic cpntrast
   c.       Contrast medium  runs into the head against gravity
   d.      It is most widely used for demonstrating the site of cerebrospinal fluid leak in cerebrospinal fluid rhinorrhoea
   e.      None of the above
   7.       Which of the following is incorrect?
   a.       Radioisotope as a method for the localisation of intracranial lesion is now obsolete
   b.      Arteriography is essential for definitive diagnosis of intracranial vascular lesion
   c.       Arteriography is useful in interventional radiology
   d.      The difference between the grey and white matter of the brain is accentuated by contrast enhanced imaging
   e.      Computed tomograpghy and magnetic resonance imaging have limited usefulness in demonstrating congenital brain lesions
   8.       Which of the following radiological terminology is matched with inappropriate modality?
   a.       CT-SCAN.............................hyperdense
   b.      MRI....................................hyperintense
   c.       X-ray..................................opacity
   d.      Ultrasound.........................isointense
   e.      Scintigraphy........................warm nodule
   9.       Radiological findings in hydrocephalus include the following except:
   a.       Enlargement of all ventricles of the brain in communicating type
   b.      Dilation of brain ventricles above the level of obstruction in non-communicating type
   c.       In infants, confirmation of hydrocephalus is usually made by arteriography
   d.      CT-scan or MRI will usually identify the level of obstruction in older patients
   e.      None of the above
   10.   The following findings are consistent with congenital aqueductal stenosis except:
   a.       Hydrocephalus involving the lateral and third ventricles
   b.      The mouth of the aqueduct of Sylvius is dilated like a trumpet or bell
   c.       There is hydrocephalus involving the fourth ventricles
   d.      No evidence of mass lesion in the brainstem
   e.      None of the above
