    Complementarity of lung scintigraphy and D-dimer test in pulmonary embolism (1997)
    Springer
    European journal of nuclear medicine 24 (1997), S. 444-447

    Notes: Abstract D-dimer assay (DDA), measuring fibrin degradation products, was compared with lung scintigraphy (LS) in a prospective unselected series of 83 consecutive patients referred owing to suspicion of pulmonary embolism (PE). This patient series was also used to compare several methods of performing and interpreting LS images. The final diagnosis was established independently by a separate panel with all available information except for the result of DDA. D-dimer was determined by ELISA (threshold value 500 ng/ml). LS, including perfusion (Q) and pseudo-ventilation (Technegas) (V), was classified according to PIOPED, (1) immediately by the physician on duty, and (2) retrospectively by a blinded panel. A positive (19) or negative (61) diagnosis of PE was achieved in 80 patients, the prevalence of PE being 24%. Only one false-negative was noted on DDA (sensitivity=95%) but there were 42 false-positives (specificity=31%), resulting in a positive predictive value of 30% and a negative predictive value of 95%. Emergency and retrospective interpretations of LS were close (kappa=0.4). In a minority of patients, PE may be excluded with reasonable certainty if DDA is normal, resulting in a significant saving in terms of time and money.

    Artifacts in camera based single photon emission tomography due to time activity variation (1987)
    Springer
    European journal of nuclear medicine 13 (1987), S. 439-442 
    Details
    ISSN: 1619-7089
    Keywords: Emission tomography ; Image distortion ; Gamma camera

    Topics: Medicine
    Notes: Abstract Image quality in single photon emission computed tomography (SPECT) using a rotating gamma camera is dependent on the time course of the tracer in the field of view. If acquisition times are slow comapred to the tracer turnover, artifacts may occur in the reconstructed images. The properties of such artifacts were studied by computer simulation. Experimental projection data of point sources, cylindrical phantoms, and an anatomically realistic brain phantom were altered by sequentially weighting the projections with a function that varied exponentially or linearly with time. The observed distortion in the reconstructed images could be related to the ratio between the object activity variation and the camera rotation time. If the tracer concentration changed less than a factor of two during one camera rotation then little image distortion was visible although quantitatively the resolution was degraded. If the object's activity variation with time is fast enough to produce noticeable distortion, the artifacts can be reduced by performing multiple, rapid, camera rotations, instead of one rotation, for the same total acquisition time. The proposed procedure is computer storage space intensive and takes longer to produce the transaxial images, but improves image quality.

    Bone scintigraphy in the diagnosis and follow up of Perthes' disease (1982)
    Springer
    European journal of nuclear medicine 7 (1982), S. 327-330 
    Details

    Topics: Medicine
    Notes: Abstract One hundred and thirty three children were studied (a total of 218 scintigrams) after IV injection of 100 μCi/kg 99mTc-MDP. Of 64 pathological hips (6 being bilateral), 52 were judged typically abnormal, 8 without initial radiological evidence. Of the rest, 8 were considered doubtful and 4 normal. No scan was considered typical of Perthes' disease in other hip disorders. The resulting figure for the sensitivity was 94%, for specificity 97%, for positive predictive value 97%, and for negative predictive value 95%. It is more difficult to assess the value of bone scintigraphy in the follow up of these patients. The disappearance of uptake defect in the femoral head may be a good index and occurs earlier than the normalization of the radiographs. On the other hand, the significance of the neighbouring regions of increased uptake is difficult to assess although related to revascularization and reconstruction. The evolution of the disease does not seem to be correlated with the localization and the intensity of these regions in a straightforward manner.

    A new unidirectional moving whole body scanner (1978)
    Springer
    European journal of nuclear medicine 3 (1978), S. 55-61 
    Details
    ISSN: 1619-7089
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract A new whole-body unidirectional moving scanner was built using a single large bar crystal, 12 photomultipliers on its top, and a delay line system to compute the X coordinate. Motion is required in only one direction on the Y-axis, and a special collimation is adapted in order to equal the X and Y performances of the detector. The performances of this detector (C.G.R. Scanicamera) (SC) were compared under the same conditions with those of a moving rectilinear scanner (R.S.) (Ohio Nuclear F 84 dual-head scanner, 12.5 cm crystal) and with an Anger gammacamera equipped with its whole body attachment (W.B.C.) (Nuclear Chicago Pho Gamma III H.P.). The general impression is that this new wholebody unidirectional moving scanner is a very convenient device for whole body studies and can also be used for large scintigraphies.

    Jugular venous reflux in cerebral radionuclide angiography: An explanation (1978)

    Notes: Abstract A case of isotopic jugular venous reflux, reaching the opposite jugular vein, is described. Phlebography and aortography were simultaneously performed in this patient and showed the innominate vein narrowed and pinched between the sternal notch and the aortic arch. This narrowing depends on the position of the left arm.
