Hysterosalpingography (HSG), also known as uterosalpingography, [1] is a radiologic procedure to investigate the shape of the uterine cavity and the shape and patency of the fallopian tubes. It is a special x-ray procedure using dye to look at the womb ( uterus ) and fallopian tubes. [ 2 ]
Unlike HSG which visualizes the fallopian tubes using X-rays, transvaginal hydrolaparoscopy provides a closer look at the fallopian tubes since the scope can be threaded directly through the tubes. [25] This procedure allows clinicians the ability to look at the inner structure of the tubes.
However, a small hydrosalpinx may be missed by sonography. During an infertility work-up a hysterosalpingogram, an X-ray procedure that uses a contrast agent to image the fallopian tubes, shows the retort-like shape of the distended tubes and the absence of spillage of the dye into the peritoneum. If, however, there is a tubal occlusion at the ...

N t is then divided by the tray efficiency, E, to determine the actual number of trays or physical plates, N a, needed in the separating column. The final design choice of the number of trays to be installed in an industrial distillation column is then selected based upon an economic balance between the cost of additional trays and the cost of ...
Falloposcopy (occasionally also falloscopy [1]) is the inspection of the fallopian tubes through a micro- endoscope. [2] The falloposcope is inserted into the tube through its opening in the uterus at the proximal tubal opening via the uterotubal junction; technically it could also be inserted at the time of abdominal surgery or laparoscopy via the distal fimbriated end.

Blockage of the fallopian tubes is mainly diagnosed today by hysterosalpingography (HSG) or Hystero Contrast Sonography (HyCoSy) in which either X-ray contrast media or aqueous fluid are forced up the fallopian tube to create an image on X-ray or ultrasound. This image demonstrates (or excludes) the possibility for sperm to swim up and for ova ...
