The emerging practice of Ultrasound.

• Definition of Ultrasound:

The emerging practice of Ultrasound.

Sound whose frequency is greater than that perceivable by humans (>20kHz)Medical Ultrasound– Imaging

• 1-12MHz (>40MHz in specialized applications)

• 1.5 mm 0.125 mm

– Therapy: • 100kHz-1MHz • Heating, cauterization, cavitation

• US Capabilities & Limitations+ Provides Real-Time imaging+ Color Doppler Non-invasive flow measurement+ Essentially non-toxic+ Inexpensive– Poor or no imaging through bone, gas– Operator dependent image quality – Images more difficult to interpret than CT

• Customer Wishes….

– What will my baby look like?

– Is it a boy or a girl?

– Is my baby healthy and normal?

2-dimensional – Female 3-dimensional – Female

2-dimensional – Male 3-dimensional – Male

• Is my baby healthy and normal??

Cleft lips at the 34 weeks.

• Some Anomalies….

The emerging practice of Ultrasound.

Thin limbs in at 17 weeks.  US reconstructed images. Small for date baby with abnormal proportion, large head and thin limbs and trunk, is demonstrated. (lower) Postmortem -CT scan image of surface anatomy (left) and bony structure (right) of the same baby.

The emerging practice of Ultrasound.

Syndactyly in a case of Apert syndrome at 31 weeks.  reconstructed images of the foot and hand. All of toes and fingers are sticked together. Postnatal appearance of foot and hand. The same appearance as prenatal imaging is seen.

• 2D V/s 3d Ultrasound.– Clearer to the untrained eye.– Mothers are better able to

recognize their baby.– Visual image, stronger

emotional connection.

Beneficial for pregnant women

More data collection than 2D Ultrasound

• Image reconstructed from single sweep across target organ
