OBJECTIVE: To construct normal ranges for umbilical artery pulsatility index (UA PI), middle cerebral artery pulsatility index (MCA PI) and cerebroplacental ratio (CPR) in prolonged pregnancies according to strict methodological criteria using polynomial regression analysis.

The MCA PI decreased as gestational age advanced from 1.97 (SD 0.48) at 20 weeks to 1.15 (SD 0.18) at We hypothesize that the uterine artery (UtA) impedance, measured by its pulsatility index (PI), exhibits a regular pattern during the normal menstrual cycle. Therefore, the main study objective was to derive normative new day-cycle-based reference ranges for the UtA-PI during the entire cycle from days 1 to 34 according to the isolated time However, few published normal ranges exist for all commonly measured fetal arterial and venous Doppler resistance and velocity parameters.Different multiple indices exist for assessing both resistance and velocity in fetal vessels. These include S/D and A/B ratios, resistance index (RI) and pulsatility index (PI). ultrasound to observe the blood flow in the lesion and to calculate Resistive index (RI) and Pulsatility index (Pl).After removal of the mass, histopathology was done for all the cases. RESULTS: On comparing histopathological and Doppler sonography findings, 54.54%patients were positive and 45.45 % were negative

To calculate the normal range for the fetal middle cerebral artery (MCA)/uterine artery pulsatility index (PI) ratio in the third trimester of pregnancy and to assess its value, compared with that of the MCA/umbilical artery PI ratio, in predicting an unfavorable outcome of … At that time, deviations below normal ranges have the poorest prognostic implications: low hepatic artery velocities (common hepatic artery velocity < 50 cm/s) and resistive indexes (common hepatic artery resistive index < 0.50), absent portal venous flow or low portal venous velocity < 30 cm/s, low hepatic venous velocity < 25 cm/s, or a monotonic hepatic venous waveform (especially in a Normal Range of Intracranial Translucency in Healthy Turkish Pregnancies and its Association with First Trimester Maternal Serum Biochemistry and Ductus Venosus Pulsatility Index. Intracranial translucency (IT) is the translucent appearance of the 4th cerebral ventricle in normal fetuses Pulsatility index (PI) is currently the most commonly used index for the evaluation of UtA Doppler waveform patterns. However, previously published studies on UtA Doppler evaluation throughout pregnancy have used a variety of Doppler indices 3,5,6,10,12,14,15,17,19 -22 or scoring systems 13,16,18 . 2021-04-10 pulsatility index: calculation of Doppler measurements of systolic and diastolic velocities in the uterine, umbilical, or fetal circulations.

The identificationof IT was possible in 167 cases in our study, The mean CRL length, gestational week, NT and IT measurements were 63.63±10.05 mm, 12.28±0.75 weeks, 1.23±0.43 mm (range: 0.20-2.68) and 2.29±0.49 mm (range: 0.18-3.80), respectively There was no significant correlation between IT and maternal serum PAPP-A MoM (r=-0.34, p=0.698) or maternal serum free β-hCG MoM (r=-0.79, p=0.363), respectively. The normal hepatic artery resistive index ranges from 0.5 to 0.7. Practical Tips The normal hepatic vein waveform demonstrates a triphasic pattern with retrograde flow during atrial contraction and two antegrade pulses during ventricular systole and ventricular diastole. ultrasound to observe the blood flow in the lesion and to calculate Resistive index (RI) and Pulsatility index (Pl).After removal of the mass, histopathology was done for all the cases.

[3] The viscosity of normal plasma varies with temperature in the same way as does that of its solvent water; a 5 °C increase of temperature in the physiological range reduces plasma viscosity by about 10%.
