Ultrasound findings prior to MRI.
Fig 1.
Magnetic resonance imaging of a 36-year-old, 32-week pregnant patient who presented with right lower quadrant pain.
A and B, Axial (A) and Coronal (B) fat saturated T2 weighted images showing a distended retrocecal appendix (arrow), a position which makes it difficult to demonstrate on ultrasonography. These findings are consistent with acute appendicitis, which was also confirmed on surgery and pathology.

Pathologies found on MRI.
Fig 3.
Coronal fat saturated T2 weighted image of a 30-year-old, 17-week pregnant patient.
There is a right-sided mild to moderate hydronephrosis with regions of parenchymal hypointensity (arrow), as well as peri-nephric fluid and fat stranding, all consistent with acute pyelonephritis.
Fig 4.
A 26-week pregnant, 34-year-old patient who presented with right lower quadrant pain.
Axial T2 weighted image (A) shows a swollen right kidney with marked hypointense lesions in the parenchyma (arrow) and a small amount of peri-nephric free fluid (arrowhead). Coronal fat saturated T2 weighted image (B) shows hypointense lesions in the right kidney’s parenchyma (arrow) and a small amount of peri-nephric free fluid (arrowhead). Findings are consistent with acute pyelonephritis.
Fig 5.
41-year-old patient, 19 weeks pregnant, who presented with right lower quadrant pain.
Axial fat saturated T1 weighted image shows hyperintense fluid at the posterior border of the right rectus abdominis muscle (arrows). This finding is consistent with rectus sheath hematoma.
