If a CT is used in conjunction of dye this is called a computerized tomography angiogram while if MRI is used it is called magnetic resonance angiogram.

If the cancer is not particularly advanced, patients may be offered careful surveillance by frequent CT scans and blood tests, in place of adjuvant treatment.

If a growth or polyp is detected using CT colonography, a standard colonoscopy would still need to be performed.

If the ultrasound shows a mass or cyst, a subsequent CT or MRI with intravenous contrast is the optimal test for diagnosis and staging.

MRI pattern of retinoblastoma with optic nerve involvement ( sagittal enhanced T1-weighted sequence ) If the eye examination is abnormal, further testing may include imaging studies, such as Computerized Tomography ( CT ), Magnetic Resonance Imaging ( MRI ), and Ultrasound.

If the bleeding is likely to have originated from an aneurysm ( as determined by the CT scan appearance ), the choice is between cerebral angiography ( injecting radiocontrast through a catheter to the brain arteries ) and CT angiography ( visualizing blood vessels with radiocontrast on a CT scan ) to identify aneurysms.

** If the D-dimer reads high, then further testing ( ultrasound of the leg veins or lung scintigraphy or CT scanning ) is required to confirm the presence of thrombus.

If not supplied, the implant surgeon makes his own or relies upon advanced computer-assisted tomography or a cone beam CT scan to achieve the proper treatment plan.

If stroke or other similar, transient disorders occur ( cerebrovascular accident, or transient ischemic attack, TIA ), then neurological imaging of the affected lobes or hemispheres of the brain can be performed ( CT, MRI, PET, etc.

If this is normal, a lumbar puncture is performed, as a small proportion of SAH is missed on CT and can still be detected as xanthochromia.

If an MRI is not available or the patient can not be placed into the scanner a CT may be used as a substitute.

If the diagnosis of sarcoidosis is suspected, typical X-ray or CT appearances of the chest may make the diagnosis more likely ; elevations in angiotensin-converting enzyme and calcium in the blood, too, make sarcoidosis more likely.

If the cysts are small and are not causing symptoms, careful observation with periodic CT scans is often done.

If esophageal perforation is suspected, even in the absence of physical findings, contrast radiographic studies of the esophagus and a CT scan should be obtained promptly.

If there is doubt about the interpretation of the Xray, stress Xrays, tomograms or CT scan may be used to make sure.

If a cracker finds a computer, they can try a port scan to detect and attack services on that computer.

If the scan time was too long, the response of the PLC to process conditions would be too slow to be useful.

If we apply the run-length encoding ( RLE ) data compression algorithm to the above hypothetical scan line, we get the following:

If they had any significant level of non-organic parts then something as simple as an x-ray scan would show them not to be human ( unless their creators designed the non-organic parts to have almost exactly the same structure and density as the organic components they were replacing, which would be both infeasible and highly improbable but not completely out of the question ).

If the TIA affects an area supplied by the carotid arteries, an ultrasound ( TCD ) scan may demonstrate carotid stenosis.

If a virus is detected, the window turns red and the scan is stopped, and the alert is shown once you exit the screensaver ) or a distributed computing application ( such as the SETI @ home project ).

If they are not, the picture will appear to jump when switching between the sources whilst the display device ( television set ) re-adjusts the horizontal and / or vertical scan to correctly reframe the image.

If the chest appears clear and SARS is still suspected, a HRCT scan will be ordered, because it is visible earlier on this scan.

If a patient is examined in another type of nuclear medicine scan but the images are non-diagnostic, it may be possible to proceed straight to SPECT by moving the patient to a SPECT instrument, or even by simply reconfiguring the camera for SPECT image acquisition while the patient remains on the table.

If results from the first ultrasound scan indicate a problem, repeating the scan 7 – 10 days later is reasonable practice.

If the diagnosis is not entirely clear from the patient's history and physical examination, a Doppler ultrasound scan can confirm increased flow of blood to the affected epididymis ( whereas tortion is characterized by ischemia ).

If a function ƒ represents an unknown density, then the Radon transform represents the scattering data obtained as the output of a tomographic scan.

If they support boundary scan, they generally build debugging over JTAG.

If the alkaline phosphatase level is above normal, other tests such as a bone-specific alkaline phosphatase test, bone scan, or X-ray can be performed.

If the anesthetic test proves positive, then a dynamic ( sit / stand ) x-ray or MRI scan may show whether the coccyx dislocates when the patient sits.

If the radio has a twenty channel scan list and some channels have CTCSS, it can take several seconds to search the entire list.

If the user transmits when the radio is in a scan mode, it may transmit on the last channel received instead of the selected channel.

If the redox couple is reversible then when the applied potential is reversed, it will reach the potential that will reoxidize the product formed in the first reduction reaction, and produce a current of reverse polarity from the forward scan.

If this is the case, then higher scan rates may show a reversible wave.

If you want a more detailed picture or a negative scan, please leave a message on my talk page.

If the circumstances are faced frankly it is not reasonable to expect this to be true.

If his dancers are sometimes made to look as if they might be creatures from Mars, this is consistent with his intention of placing them in the orbit of another world, a world in which they are freed of their pedestrian identities.

If a work is divided into several large segments, a last-minute drawing of random numbers may determine the order of the segments for any particular performance.

If they avoid the use of the pungent, outlawed four-letter word it is because it is taboo ; ;

If Wilhelm Reich is the Moses who has led them out of the Egypt of sexual slavery, Dylan Thomas is the poet who offers them the Dionysian dialectic of justification for their indulgence in liquor, marijuana, sex, and jazz.

If he is the child of nothingness, if he is the predestined victim of an age of atomic wars, then he will consult only his own organic needs and go beyond good and evil.

If it is an honest feeling, then why should she not yield to it??

If he thus achieves a lyrical, dreamlike, drugged intensity, he pays the price for his indulgence by producing work -- Allen Ginsberg's `` Howl '' is a striking example of this tendency -- that is disoriented, Dionysian but without depth and without Apollonian control.

If love reflects the nature of man, as Ortega Y Gasset believes, if the person in love betrays decisively what he is by his behavior in love, then the writers of the beat generation are creating a new literary genre.

If he is good, he may not be legal ; ;

If the man on the sidewalk is surprised at this question, it has served as an exclamation.

If the existent form is to be retained new factors that reinforce it must be introduced into the situation.

If we remove ourselves for a moment from our time and our infatuation with mental disease, isn't there something absurd about a hero in a novel who is defeated by his infantile neurosis??

If many of the characters in contemporary novels appear to be the bloodless relations of characters in a case history it is because the novelist is often forgetful today that those things that we call character manifest themselves in surface behavior, that the ego is still the executive agency of personality, and that all we know of personality must be discerned through the ego.

If he is a traditionalist, he is an eclectic traditionalist.

If our sincerity is granted, and it is granted, the discrepancy can only be explained by the fact that we have come to believe hearsay and legend about ourselves in preference to an understanding gained by earnest self-examination.

If to be innocent is to be helpless, then I had been -- as are we all -- helpless at the start.
