Basic physical principles of nuclear magnetic resonance imaging (N.M.R.I), a nonionizing medical imaging technique, are described. Principles of NMRI with other conventional imaging methods, ie, isotope scanning, ultrasonography and radiography have been compared. T1 and T2 and spin density (S.D.) factors and different image construction techniques based on their different combinations is discu...
متن کاملAssessment of the Lens Anterior–Posterior Diameter as Compared with the Eye Globe by Ultrasonography in Rabbit
Objective- Assessment of the lens anterior – posterior (AP) diameter as compared with the eye globe by ultrasonography in rabbit. Design- Descriptive study. Animals- 120 male and female rabbits, two months to four years old, and weighting between 300 to 1500gr. Procedures- 2D ultrasonography of the eyes was performed and AP diameter of the eyes and lens were measured using Sonosite Tit...
متن کاملEvaluation of Ultrasonography and Mammography in Diagnosis of Mammary Gland Tumor in Bitches: Based on Tumor Markers
Objective- This study refers to the role of ultrasonography in the diagnosis of mammary gland tumor in bitches as a complementary diagnostic method and its ultimate goal is to evaluate the results of mammography with the positive results of ultrasonography. Design- Prospective study. Animals- 12 German Shepherd bitches with swollen mass in the mammary gland region (group I) and 12 h...
متن کاملCurrent-induced spin-wave Doppler shift.
Spin transfer appears to be a promising tool for improving spintronics devices. Experiments that quantitatively access the magnitude of the spin transfer are required for a fundamental understanding of this phenomenon. By inductively measuring spin waves propagating along a permalloy strip subjected to a large electrical current, we observed a current-induced spin wave Doppler shift that we rel...
متن کاملInverse correlation between cerebral blood flow measured by continuous arterial spin-labeling (CASL) MRI and neurocognitive function in children with sickle cell anemia (SCA).
Overt stroke, clinically "silent" cerebral infarct, and neurocognitive impairment are frequent complications of sickle cell anemia (SCA). Current imaging techniques have limited sensitivity and specificity to identify children at risk for neurocognitive impairment. We prospectively evaluated 24 children with SCA with a neurologic exam, complete blood count, transcranial Doppler ultrasound (TCD)...
