Whole-body 18F-FDG PET/CT scan in a patient with Ovarian Cancer taken from the PETWB-REP dataset. The following English report (translated from original Chinese) is taken verbatim from the public dataset and has not been modified or otherwise checked for accuracy (see the end for citation).

Findings

After fasting and intravenous injection of 18F-FDG, and resting, a whole-body PET/CT scan was performed.
The whole-body images showed: Normal brain morphology and structure; no abnormal density shadows were seen in the brain parenchyma; FDG uptake was normal.
No widening was observed in the ventricles, sulci, fissures, or cisterns; local density and FDG uptake were normal; and midline shift was not observed.
The bilateral eyeballs showed normal morphology and outline; retrobulbar structures were clear; and FDG uptake was normal.
Slight thickening of the mucosa in the right maxillary sinus was observed; the mucosa of the other paranasal sinuses showed no thickening, and the sinus walls were intact.
No significant thickening of the soft tissue on both sides of the nasopharyngeal wall was observed; the bilateral pharyngeal recesses were symmetrical; and FDG uptake was normal.
FDG uptake in the bilateral palatine tonsils was physiological.
The laryngopharynx showed normal morphology and structure; the parapharyngeal space was clear.
The bilateral parotid and submandibular glands showed normal size, shape, and density; and FDG uptake was physiological.
The thyroid gland is normal in shape and size, but its density is somewhat heterogeneous.
Two thyroid-like density nodules are seen in the posterior part of the right lobe, the larger one being approximately 1.1 cm in length.
FDG uptake is normal.
No significantly enlarged lymph nodes are seen in the bilateral deep cervical spaces, submandibular region, or submental region.
FDG uptake is normal in these areas.
Postoperatively, linear dense shadows and patchy linear shadows are seen in the surgical area and adjacent pleura, predominantly in the right upper lobe.
The surrounding bronchi are tortuous, dilated, and distally occluded.
FDG uptake is increased, with SUVmax = 2.1.
Several ground-glass nodules are seen in the lower lobes of both lungs.
The largest one is located in the posterior segment of the right lower lobe, with a length of approximately 0.4 cm and indistinct borders.
The largest CT value is approximately -669 HU.
FDG uptake is normal in these areas.
Several small nodules (diameter < 0.3 cm) are also seen in both lungs, with clear borders.
FDG uptake is normal in these areas.
A few patchy and linear shadows are also seen in both lungs.
FDG uptake is normal in these areas.
Slight thickening of the pleura was observed in some areas, but no significant pleural effusion was seen in either pleural cavity.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions, and FDG uptake was not significantly increased.
The heart size was normal.
The fibrous glands in both breasts were dense, and FDG uptake was normal.
The liver was normal in shape and size, with smooth borders and no widening of the hepatic fissures.
Patchy, roundish low-density lesions were observed in the left lobe of the liver, the largest being approximately 0.7 cm in long diameter, with relatively clear borders, and FDG uptake was normal.
No dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder was normal in shape and size, with no thickening of the gallbladder wall, no positive stones or obvious masses, and FDG uptake in the gallbladder fossa was normal.
The peripancreatic spaces were clear, with no significant abnormal density shadows in the parenchyma, no widening of the pancreatic duct, and no abnormal FDG uptake.
The spleen was basically normal in shape and size, with no abnormal density or FDG uptake.
The bilateral adrenal glands were normal in shape, size, and density, and local FDG uptake was normal.
Both kidneys are normal in shape and size.
The right kidney shows punctate dense shadows in the parenchyma, with no significant abnormalities in FDG uptake.
No widening of the renal pelvis, calyces, or ureters is observed, and no positive stones are seen locally.
The bladder is poorly filled, but no positive stones are seen within the lumen.
The esophagus is not dilated, but the lower segment wall is slightly thickened, with increased FDG uptake (SUVmax = 5.5).
The stomach is well-filled, with slight thickening of the antral wall and increased FDG uptake (SUVmax = 4.5).
The intestines are not satisfactorily filled, with no localized masses, but some intestinal segments show increased FDG uptake (SUVmax = 6.2).
A large cystic-solid mass measuring approximately 18.1 13.9 23.3 cm is seen in the abdominopelvic cavity.
It is a single cyst with a thin wall.
Patchy and nodular soft tissue density shadows are seen along the inner edge of part of the cyst wall, with increased FDG uptake (SUVmax = 13.8).
Most of the cyst wall has clear borders, except for a portion at the lower right margin, where the boundary with the remaining cervix is unclear.
The uterus was absent post-operatively.
No enlarged lymph nodes were observed in the abdominal cavity, pelvic cavity, or retroperitoneal region, and FDG uptake was not increased.
No significant fluid accumulation was observed in the abdominal cavity or pelvic cavity.
The spinal alignment was normal, with some vertebral body margin osteophytes and significant calcification of the posterior longitudinal ligament at the C5/6 level; FDG uptake was not abnormal.

Impression

1. A large cystic-solid mass in the abdominopelvic cavity with significantly increased FDG metabolism in the solid portion, suggestive of malignancy, most likely ovarian cancer; please confirm with pathology.

2. a. Postoperative changes in the right lung; no signs of tumor recurrence were observed in the surgical area; please compare with old films and follow up with CT. b. Chronic inflammatory ground-glass nodules or atypical adenomatous hyperplasia in the lower lobes of both lungs; chronic inflammatory solid micronodules in both lungs; please have an annual HRCT follow-up. c. A few chronic inflammations and remnants in the remaining lungs. Hyperplastic changes in both breasts.

3. Chronic inflammatory changes in the lower esophagus and stomach; some intestinal physiological uptake. Small liver cysts. Punctate calcifications in the right kidney.

4. Degenerative changes in the spine; significant calcification of the posterior longitudinal ligament at the C5/6 level.

5. No obvious abnormalities were seen on cranial scintigraphy. A few chronic inflammations in the right maxillary sinus.

6. A nodular lesion posterior to the right lobe of the thyroid gland (density similar to the thyroid gland); no increased FDG metabolism was observed; suggestive of a posterior thyroid nodule; please confirm with ultrasound.

This case is from PETWB-REP, a curated dataset of whole-body 18F-FDG PET/CT scans and corresponding radiology reports from 490 patients with a broad spectrum of malignancies. The data were retrospectively collected from patients who underwent clinically indicated whole-body 18F-FDG PET/CT scans at the Shanghai Universal Medical Imaging Diagnostic Center between 2021 and 2024.
