Sono HSG is a simple, well-tolerated ultrasound procedure used to evaluate the patency of the fallopian tubes, as well as detect abnormalities of the uterus. The procedure usually takes between 10 and 30 minutes to complete and the results are available immediately.
Sonohysterography can find the underlying cause of many problems, including abnormal uterine bleeding, infertility, and repeated miscarriage. It is able to detect the following:
Abnormal growths inside the uterus, such as fibroids or polyps, and information about their size and depth
Scar tissue inside the uterus
Abnormal uterine shape
Problems with the lining of the uterus
Whether the fallopian tubes are open or blocked
This procedure is performed between cycle day 5-12, cycle day 1 is the first day of full flow of your menstrual cycle. There is no special preparation needed for the exam, although you may want to empty your bladder prior to the test. You may experience some discomfort with this procedure. You may take Tylenol, Advil or Motrin one hour prior to the procedure to decrease any cramping which may occur. Occasionally, prophylactic antibiotics may be prescribed, if you have a known history of pelvic infections

MR Hysterosalpingography with an Angiographic Time-Resolved 3D Pulse Sequence: Assessment of Tubal Patency
The purpose of our study was to determine if tubal patency can be assessed by MR hysterosalpingography (HSG) using a clinically available MR angiographic sequence (3D time-resolved imaging of contrast kinetics [TRICKS]). This capability would enhance the value of MRI in women with infertility.
MR HSG effectively shows tubal patency and can be considered when both conventional HSG and standard MRI are necessary for the evaluation of women with infertility, such as in women with suspected uterine anomalies or extrauterine disease.
MRI was performed on a 1.5-T system (Signa,
GE Healthcare), using a four-element phased-
array surface coil. T1-weighted and T2-weighted
images using routine clinical parameters were
obtained to assess for intra- and extrauterine
abnormalities. Then the patient was taken out of
the MR scanner and brought to a procedure room
where an HSG catheter (Hystero-Salpingography
Catheter 5F, Medical Device Technologies)
attached to IV tubing (Clearlink System, 44-inch
[111.8-cm] extension set, Baxter Healthcare), was
placed by the radiologist or referring gyneco-
logist. After catheter placement, the patient was
returned to the MR scanner for the remainder of
the examination.
approximately 20–40 mL of
a 1:100 mixture of gadodiamide (Omniscan, GE
Healthcare) to normal saline (0.9%) was gently
hand-injected during a multiphase acquisition
using a clinically available, dynamic time-resolved
T1-weighted angiographic sequence (3D TRICKS).
The optimal dilution was determined through our
institutional clinical experience with MR arthro-
graphy. An oblique axial plane through the pelvis to
include the uterus, ovaries, and cul-de-sac was
prescribed using the following parameters: TR/TE,
4.5/minimum; number of excitations, 0.7; matrix,
256 × 128; and field of view, 26–28 cm.
TRICKS acquisitions; one set was acquired with a
slice thickness of 4.4 mm and a temporal resolution
of 2.2 seconds, and the second set was acquired
with a slice thickness of 5.4 mm and a temporal
resolution of 1.8 seconds. A final axial T1-
weighted, fat-suppressed 3D spoiled gradient-
echo series was obtained. After the study was
complete, 20–40 mL of normal saline was used to
flush the uterus. The entire MRI examination
lasted 60 minutes or less, which included the time
required to place the HSG catheter
