    Cerebral NMR: diagnostic evaluation of brain tumors by partial saturation technique with resistive NMR (1985)
    Springer
    Neuroradiology 27 (1985), S. 9-15

    ISSN: 1432-1920
    Keywords: NMR ; MRI ; resistive and brain tumors

    Topics: Medicine
    Notes: Summary One hundred and forty patients with cerebral neoplasms were examined in a 0.12-Tesla prototype resistive NMR proton imaging device by partial saturation technique. NMR was superior to CT in tumor and edema localization and equal to CT in tumor and edema detection. NMR, however, was not able to clearly separate tumor from edema, a separation that contrast enhanced CT achieved.

    Application of contrast agents in CT and MRI (NMR): their potential in imaging of brain tumors (1985)
    Springer
    Neuroradiology 27 (1985), S. 164-171

    Notes: Summary 21 patients with clinical and CT diagnoses of intracranial tumor were studied by MRI (NMR) prior to and after administration of intravenous Gadolinium-DTPA. Resultant MRI images were compared with corresponding CT sections with respect to lesion detection, contrast enhancement, tumor delineation and visualization of perifocal edema. All intracranial lesions shown on CT were identified on MRI. Contrast enhancement in MRI images was achieved in 19 out of 21 patients, as it was also with CT. In these cases improved differentiation between tumor, perifocal edema and adjacent brain structures were obtained. In most cases sufficient visualization of perifocal edema in MRI required T2 weighted images (SE 1600/70) in addition to spin echo scans routinely performed prior to and after contrast medium (SE 400/30 or 800/30). No side effects were encountered following administration of Gadolinium-DTPA. The good tolerance and the efficacy justifies the use of Gadolinium-DTPA for contrast enhanced MRI imaging.

    MRI (NMR) in the diagnosis of brain-stem tumors (1985)
    Springer
    Neuroradiology 27 (1985), S. 208-213 
    Details
    ISSN: 1432-1920
    Keywords: MRI ; NMR ; brain stem ; brain tumor
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary Patients with a brain-stem tumor were studied with NMR. The full extent of the lesion as well as its relationship with the adjacent structures was clearly demonstrated in all cases. Although NMR is, in many aspects, superior to CT and angiography, these examinations remain useful complementary methods.

    NMR imaging of congenital intracranial germinal layer neoplasms (1985)
    Springer
    Neuroradiology 27 (1985), S. 301-303 
    Details
    ISSN: 1432-1920
    Keywords: NMR ; MRI ; epidermoid tumors ; dermoid tumors
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary NMR images in five patients with surgically proved, congenital germinal layer intracranial neoplasms (two dermoid and three epidermoid tumors) were reviewed. The dermoids were typically midline (suprasellar or parapineal) masses with sharply-defined margins. Relaxation times were variable, but if fat was present, T1 was decreased, and T2 was increased. The epidermoids were off the midline (cerebellopontine angle, temporal lobe, frontal lobe) masses with generally long T1 and T2 relaxation times. Obstructive hydrocephaly was noted in one patient, and tumor to ventricular communication was demonstrated in another.
