Questions 18 through 21 refer to the figure below of an axial MRI of the female pelvis.Which arrow points to the ovary?
Correct Answer
C. A
Explanation
The arrow labeled A points to the ovary. The ovary is a part of the female reproductive system located in the pelvis. It is responsible for producing and releasing eggs, as well as producing hormones such as estrogen and progesterone. In the given axial MRI image, arrow A is pointing to a structure that matches the location and appearance of an ovary.

Questions 28 through 31 refer to the figure below of a 3D CT of the pelvis.Which arrow points to the L5 vertebra?
Correct Answer
C. A
Explanation
In the given figure, the arrow labeled "A" points to the L5 vertebra.
3.
The uterus:
Correct Answer
A. It is usually bent forward over the upper surface of the urinary bladder
Explanation
The correct answer is that the uterus is usually bent forward over the upper surface of the urinary bladder. This is known as anteversion, and it is a normal anatomical position of the uterus. The position of the uterus can vary slightly among individuals, but in most cases, it is tilted forward. This position allows for proper alignment with the vaginal canal and facilitates the passage of menstrual blood and sperm.

Questions 13 through 16 refer to the figure below of a coronal MRI of the female pelvis.Which arrow points to the urogenital diaphragm?
Correct Answer
B. D
Explanation
The urogenital diaphragm is a layer of muscles and connective tissue that separates the pelvic cavity from the perineum. In the given figure, arrow D points to a structure that is located at the level of the urogenital diaphragm. Therefore, arrow D is the correct answer.
5.
Questions 44 through 47 refer to the figure below of a sagittal, T2-weighted MRI of the female pelvisWhich arrow points to the uterine cavity?
Correct Answer
B. A
Explanation
The arrow pointing to the uterine cavity is A. This can be determined by examining the image and identifying the structure that corresponds to the uterine cavity. The uterine cavity is the central space within the uterus where the fetus develops during pregnancy. In the given image, arrow A is pointing to the central space within the uterus, indicating the uterine cavity.

Questions 72 through 75 refer to the figure below of an axial, T2-weighted MRI of the male pelvis.Which arrow points to the penile urethra?
Correct Answer
D. A
Explanation
The arrow pointing to A indicates the penile urethra in the axial, T2-weighted MRI of the male pelvis.
7.
Questions 13 through 16 refer to the figure below of a coronal MRI of the female pelvis.Which arrow points to the uterosacral ligament?
Correct Answer
B. A
8.
Place the following female pelvic structures in proper sequence from anterior to posterior: (1) posterior fornix; (2) urinary bladder; (3) rectum; (4) cervix; (5) pubic bone.
Correct Answer
B. 5, 2, 4, 1, 3
Explanation
The correct sequence for the female pelvic structures from anterior to posterior is as follows: pubic bone, urinary bladder, cervix, posterior fornix, and rectum. This sequence starts with the pubic bone, which is located at the front of the pelvis, followed by the urinary bladder, which is located just behind the pubic bone. The cervix comes next, as it is positioned towards the middle of the pelvic cavity. The posterior fornix is located behind the cervix, and finally, the rectum is the most posterior structure in the sequence.
9.
Which of the following does not contribute to the formation of the os coxae?
Correct Answer
C. Sacrum
Explanation
The os coxae, also known as the hip bone, is formed by the fusion of three bones: the pubis, ischium, and ilium. The sacrum, on the other hand, is a triangular bone located at the base of the spine, and it does not contribute to the formation of the os coxae. Therefore, the correct answer is Sacrum.

Questions 76 through 79 refer to the figure below of an MRA of the descending aorta.Which arrow points to the right common iliac artery?
Correct Answer
A. C
11.
Questions 80 through 83 refer to the figure below of an axial, T1-weighted MRI of the right hip.Which arrow points to the tensor fascia latae muscle?
Correct Answer
B. A
Explanation
The correct answer is A. The tensor fascia latae muscle is a small muscle located on the lateral aspect of the hip. In the given MRI image, arrow A points to a muscle that is located on the lateral aspect of the hip, which is consistent with the location of the tensor fascia latae muscle. Arrows B, C, and D do not point to muscles in the lateral aspect of the hip, so they are not the tensor fascia latae muscle.

Questions 36 through 39 refer to the figure below of an axial, T1-weighted MRI of the male pelvis.Which arrow points to the sciatic nerve?
Correct Answer
D. D
13.
Questions 52 through 55 refer to the figure below of an axial CT of the male pelvis.Which arrow points to the spermatic cord?
Correct Answer
D. A
Explanation
Arrow A points to the spermatic cord.
14.
Questions 44 through 47 refer to the figure below of a sagittal, T2-weighted MRI of the female pelvis.Which arrow points to the pubic symphysis?
Correct Answer
C. C
Explanation
Arrow C points to the pubic symphysis. The pubic symphysis is the joint between the two pubic bones in the pelvis. In the given MRI image, arrow C is clearly pointing to the area where the two pubic bones meet, indicating the location of the pubic symphysis.
