Renograma 99mTc Post-Captoprilen la valoración de la hipertensión vásculo-renal en pacientes portadores de injerto renal.

Objectiu: Descripció de la metodologia del renograma isotòpic basal/postcaptopril (RIB/P) en pacients portadors de empelt renal amb sospita de malaltia vasculo-renal (MVR). Material i mètodes: Es va realitzar en 44 pacients trasplantats renals un renograma basal i 48 hores després un renograma postcaptopril administrant 25 mg de captopril v.o i realitzant una adquisició 30 minuts després. Resultats: Dels 44 estudis 6 van ser positius, constatant-se MVR per angio-TC i 38 van ser negatius tractats posteriorment amb IECAs o ARAII i no van mostrar alteracions significatives del funcionalisme renal. Conclusions: El RIB/P es una eina útil para determinar MVR en pacients amb empelt renal i hipertensió arterial.

Role of technetium-99m diphosphonate and gallium-67 citrate bone scanning in the early diagnosis of infectious spondylodiscitis: a comparative study

A comparative study of the parts played by technetium-99m diphosphonate and gallium-67 citrate bone scanning in the early diagnosis of infectious spondylodiscitis is presented. Nineteen patients were included in the study. All patients (11 men aged 19-70 years and eight women aged 18-72 years) had a history of back pain varying in duration from one to 15 weeks. A 99mTc diphosphonate bone scan was positive in 17 patients. The two patients with negative results had less than two weeks of back pain. The 67Ga citrate bone scan showed uptake in all patients.

Dynamic and quasistatic trajectories in quasifission reactions and particle emission

We show that the quasifission paths predicted by the one-body dissipation dynamics, in the slowest phase of a binary reaction, follow a quasistatic path, which represents a sequence of states of thermal equilibrium at a fixed value of the deformation coordinate. This establishes the use of the statistical particle-evaporation model in the case of dynamical time-evolving systems. Pre- and post-scission multiplicities of neutrons and total multiplicities of protons and α particles in fission reactions of 63Cu+92Mo, 60Ni+100Mo, 63Cu+100Mo at 10 MeV/u and 20Ne+144,148,154Sm at 20 MeV/u are reproduced reasonably well with statistical model calculations performed along dynamic trajectories whose slow stage (from the most compact configuration up to the point where the neck starts to develop) lasts some 35×10−21 s.
