An mother who is an intravenous drug abuser (IVDA) was referred for an obstetrical sonogram.  She had no prior prenatal care. The image above was obtained of the fetal head at the level of the BPD .  What is the MOST likely explanation for the sonographic findings?

An initial exposure is made using 800 mA, 0.02 sec, 16 mAs, 70 kVp, 58” SID, 4 “ OID, 5:1 grid ratio, 0.2 mm focal spot, 3.0 mm of filtration, and a 14 x 17 in field size. If the technologist changes the mAs to 5 for a second exposure without changing any other factors, what differences would you expect to see in the second exposure?1. increased IR exposure2. decreased IR exposure3. increased contrast4. decreased contrast5. increased spatial resolution6. decreased spatial resolution7. increased distortion8. decreased distortion
