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 scan showed: The brain morphology and structure were normal, with no abnormal density shadows in the brain parenchyma, and no significant abnormalities in FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
The nasal septum was deviated, but the nasopharyngeal wall was not thickened, and FDG uptake was normal.
The pharyngeal recesses were symmetrical bilaterally, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear, with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx morphology and structure were normal.
Thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
Lung markings are clear.
Several solid nodules are present in the left lung and the lateral segment of the middle lobe of the right lung, the largest being approximately 0.3 cm in diameter; FDG uptake is normal.
Calcification is present in the left upper lobe, and scattered linear lesions are present in both lungs; FDG uptake is normal.
No pleural thickening is seen bilaterally, and there is no pleural effusion or pneumothorax bilaterally.
Several calcifications are present in the mediastinum.
Cardiac silhouette is normal.
Partial arteriosclerosis is present.
Both breasts have dense glandular tissue; calcification is present in the right breast; FDG metabolism is normal.
The esophagus is not dilated, and the esophageal wall is not significantly thickened or lumped; FDG uptake is normal.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissure.
Several cystic lesions were observed within the liver, the largest being located in the left lateral lobe, approximately 1.3 cm in diameter.
FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape and size, with no thickening of the gallbladder wall and no abnormalities in localized FDG uptake.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct was not widened, and FDG uptake was normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size.
A cystic lesion was observed in the lower pole of the right kidney, approximately 1.1 cm in diameter.
FDG metabolism was normal.
The renal pelvis, calyces, and ureter were not widened, and FDG uptake was normal.
Bilateral adrenal gland imaging showed no obvious abnormalities.
Stomach distension is inadequate, with slight thickening of the cardia, part of the gastric body, and antrum walls.
FDG uptake is mildly increased, SUVmax=2.1.
Intestinal distension is unsatisfactory, with a considerable amount of residual contents in the intestinal lumen; intestinal uptake is physiological.
Uterus is normal in shape and size, with no abnormal density shadows, and FDG uptake is normal.
Bladder distension is inadequate, with no obvious positive stones.
Following bilateral adnexectomy and peritoneal lesion resection, FDG uptake around the midline abdominal incision is increased, SUVmax=4.2; the surgical area structures are slightly disordered, with thickening of the greater omentum, mesentery, and pelvic floor fascia accompanied by a few flocculent shadows; FDG metabolism is normal; a small amount of pelvic effusion is present.
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies, L4/5 intervertebral disc bulging with posterior margin calcification.
Schmorl's node is present at the superior margin of the T12 vertebral body.
No abnormalities were found in FDG metabolism throughout the bone marrow.

Impression

1. a. Postoperative changes in the abdominal wall following bilateral adnexal and peritoneal lesion resection, thickening of the greater omentum, mesentery, and pelvic floor fascia with a few flocculent shadows. FDG metabolism was normal. Postoperative changes are considered possible, but metastatic tumors need to be ruled out. Please correlate with clinical findings and conduct regular follow-up examinations. Small amount of pelvic effusion. b. No obvious space-occupying lesions were found in the liver, gallbladder, or pancreas. Enhanced MRI of the upper abdomen should be performed if necessary to rule out occult lesions.

2. Chronic inflammatory micronodules in both lungs. Calcification in the left upper lobe of the lung, a few post-inflammatory remnants in both lungs. Mediastinal calcification. Partial arteriosclerosis.

3. Bilateral breast hyperplasia, calcification in the right breast.

4. Multiple liver cysts. Right kidney cyst.

5. Possible chronic inflammatory changes in the gastric wall; please combine with endoscopic examination to rule out other possibilities.

6. Degenerative changes in the spine, L4/5 intervertebral disc bulge with posterior calcification. Schmorl's node at the superior margin of the T12 vertebral body.

7. No obvious abnormalities were found on cranial scintigraphy.

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.
