“…In the detection of perisellar lesions NMR has proved superior to CT in a number of cases of our own series as well as in the literature [5,7,8]. The direct multiplanar imaging capability of MR in combination with its high tissue contrast and the lack of bone artefacts are considered its main diagnostic advantages in the region of the sella.…”

“…Because of severe bone artefacts the lesion was almost missed in the CT. In the paramedian sagittal sections of M R which were performed with short and long imaging parameters of SE as well as with IR, the lesion developed significant differ- ences in contrast compared to its surrounding tissue because of prolonged T I and T2 values [5,13] making its diagnosis easy (Figs. 6a, b).…”

Nuclear magnetic resonance (NMR) imaging is a versatile technique which has proved more sensitive in the detection of perisellar lesions than CT. A multiplanar facility, the demonstration of blood flow, and the lack of bone artefacts are its main advantages in this respect. Limitations are seen in its inability to identify small calcifications and to distinguish clearly perifocal oedema and tumour especially in malignant lesions. Relatively thick slices of 5-10 mm make the detection of microadenomas very difficult, mainly because of partial volume effects. T1 and T2 values alone are not sufficient to provide specific diagnosis. No reliable criteria have been determined yet, which would indicate the quality of pathological involvement of peritumorous structures by tumours of the sella region. At present NMR still plays a more complementary role to CT in the evaluation of this complex anatomical area. We are confident that with future technical refinements NMR will be able to replace ionizing radiation for the diagnostic imaging of the sella.

“…A pesar de la gran precisión que han proporcionado los avances en las técnicas radiológicas de neuroimagen 8,11,19 , el diagnóstico de invasión del seno cavernoso continúa dependiendo con frecuencia de los hallazgos intraoperatorios 7 . Se han propuesto diferentes clasificaciones para intentar definir el grado de extensión parasellar de los macroadenomas.…”

“…Aunque las nuevas técnicas de resonancia magnética (RM) permiten una mejor definición de las estructuras anatómicas del espacio paraselar 8,11,19 continúan siendo poco sensibles para definir con certeza la invasión de éste y en especial del seno cavernoso 7,14 . Los factores anatómicos y estructurales de la pared medial del seno cavernoso parecen jugar un papel fundamental en la invasión tumoral.…”
