Class 2 Flashcards
What can be visualized in Female Pelvic Ultrasound?
UTERUS OVARIES FALLOPIAN TUBES (if dilated) VAGINA GRAVID UTERUS
Transabdominal Pelvic Exam Patient Prep
- 32 OUNCES OF WATER FINISHED 1 HOUR PRIOR TO EXAM
- ADJUST FOR POSTMENOPAUSAL PATIENT TO 24 OUNCES
Reasons for Bladder Filling
- Pushes bladder superiorly
- Decreases angle of incidence
- Pushes loops of bowel out of view
- Provides acoustic window for uterus & adnexa
- Provides anatomic reference point
- Provides for assessment of mass mobility
- Provides for mass comparison
The Transabdominal Pelvic Exam: Transducer and patient position?
TRANSDUCER: 3.5 MHZ TO 5.0 MHZ
PATIENT POSITION: SUPINE
Transvaginal Pelvic Exam: Patient Prep
PATIENT PREP:
- EMPTY URINARY BLADDER
- DISROBE FROM WAIST DOWN
- ELEVATE HIPS, IF GYNECOLOGY TABLE NOT AVAILABLE
- PREPARE THE PROBE
- INSERT THE PROBE OR ASK THE PATIENT TO INSERT THE PROBE LIKE A TAMPON
- MALE SONOGRAPHERS MUST HAVE A FEMALE CHAPERONE PRESENT DURING THE EXAM!
Transvaginal Ultrasound Advantages
- Better resolution
- Can measure and analyze smaller structures
- No need for bladder filling
Transvaginal Ultrasound Disadvantages
- Smaller more limited field of view due to frequency and limitations in probe movements
- Invasive
Obstetric Exam: Patient Prep:
- DEPENDS ON GESTATIONAL AGE
- BEFORE WEEK 15; 32 OUNCES OF WATER
- AFTER WEEK 15; 16 OUNCES OF WATER
Transperineal Scanning: When is it used and why?
- SCANNING BETWEEN LABIA AND PERINEUM
- PATIENT POSITION SAME AS TRANSVAGINAL EXAM
- USEFUL WHEN TRANSVAGINAL US IS CONTRAINDICATED
What is Sonohysterography?
- 25-30 ml of sterile saline in endometrial cavity
- Delineates endometrial cavity
- Used in evaluation of endometrial polyps, fibroids, endometrial hyperplasia, and patency of fallopian tubes
What are Contrast Agents?
- ECHOVIST VIA CATHETER INSERTION
- IV CONTRAST AGENTS
- IV CONTRAST AGENTS ENHANCE COLOR AND PULSED WAVE CHARACTERISTICS IN SMALL VESSELS
What is Three Dimensional Imaging?
-CURRENT DEVELOPMENT AND INVESTIGATION ON-GOING
PRO-VIDES TOPOGRAPHICAL IMAGING INFORMATION
-USEFUL IN EVALUATION OF FACE, DIGITS, LIMBS, AND NEURAL TUBE DEFECTS
What are the Sonographer’s Responsibilities?
- PROPER EQUIPMENT
- REDUCE PATIENT DISCOMFORT
- MINIMIZE EXPOSURE TO ULTRASOUND
- PROVIDE THOROUGH AND SYSTEMATIC EXAMINATIONS
- ADHERE TO THE SONOGRAPHER’S CODE OF CONDUCT
- ACHIEVE REGISTRATION THROUGH THE ARDMS
- STAY CURRENT ON EMERGING TRENDS WITH CONTINUING MEDICAL EDUCATION
