Whole-body 18F-FDG PET/CT scan in a patient with Lung 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, a whole-body PET/CT scan was performed.
The whole-body scan showed: Normal brain morphology and structure; no abnormal density shadows were seen in the brain parenchyma; no significant abnormalities in FDG uptake were observed.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical and showed no significant abnormalities.
Slight thickening of the right maxillary sinus mucosa was observed, but the sinus wall was intact.
No thickening of the nasopharyngeal wall was observed; no abnormalities in FDG uptake were observed; the pharyngeal recesses were symmetrical; there was no narrowing of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the bilateral parapharyngeal spaces were clear, and no abnormalities in FDG uptake were observed.
Both palatine tonsils showed physiological uptake.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
Increased FDG metabolism was observed in the left tip of the tongue and both sides of the laryngopharynx, with SUVmax = 6.7.
The thyroid gland was normal in morphology and size, with uniform density; no abnormalities in FDG uptake were observed.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region; FDG metabolism was normal.
An irregular nodule measuring approximately 2.8 2.0 cm was observed in the posterior basal segment of the right lower lobe, with uneven wall thickness, multiple small cavities, and irregularly shaped margins with visible fine spiculations; FDG metabolism was elevated (SUVmax = 6.2).
Multiple focal low-density areas without pulmonary markings were observed in both lungs; a small air-filled cystic cavity approximately 0.7 cm in diameter was observed in the apical segment of the right upper lobe; FDG metabolism was normal.
Scattered multiple pure ground-glass nodules were observed in both lungs, with relatively clear borders, most prominent in the left upper lobe, with a maximum diameter of approximately 0.5 cm; FDG uptake was normal.
Several solid small nodules, approximately 0.2-0.3 cm in long diameter, were also observed in the left and right middle lobes; FDG metabolism was normal.
A high-density shadow was observed in the anterior basal segment of the left lower lobe; FDG metabolism was normal.
No thickening of the pleura was observed bilaterally, and there was no effusion or pneumothorax in either pleural cavity.
No significantly enlarged lymph nodes were observed in the bilateral hilum and mediastinum.
The cardiac silhouette was normal.
The esophagus was not dilated, and the wall was not significantly thickened or swollen; FDG uptake was not increased.
The breasts were relatively dense bilaterally, and FDG metabolism was normal.
The liver was normal in shape and size, with smooth borders, no widening of the hepatic fissure, and no significant abnormal density shadows in the liver parenchyma on plain CT scan; FDG uptake was normal.
The main portal vein was not significantly widened, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder was normal in shape and size, with no thickening of the gallbladder wall; local FDG uptake was normal.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma; the main pancreatic duct was not widened; FDG uptake was normal.
The spleen was normal in shape, size, density, and FDG uptake.
The left renal axis was deviated to the right, and the renal hilum was everted; FDG uptake was physiological.
The right kidney is normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
There is no widening of the renal pelvis, calyces, or ureter, and FDG uptake is normal.
Bilateral adrenal gland imaging shows no obvious abnormalities.
The stomach is poorly distended, with no obvious thickening of the gastric wall, and FDG uptake is normal.
The intestines are poorly distended, with no obvious thickening or mass in the intestinal wall, and FDG uptake is physiological.
The uterus is full in shape with an irregular outline, and FDG uptake is normal.
A cystic lesion measuring approximately 2.8 2.3 cm is seen in the left adnexa, with relatively clear borders; FDG metabolism is normal.
No abnormal FDG metabolism is seen in the right adnexa.
The bladder is generally distended, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdominal cavity, pelvis, or retroperitoneal region, and FDG metabolism is normal.
No obvious fluid accumulation is seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with some vertebral marginal osteophytes; FDG uptake is normal.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. A mass in the posterior basal segment of the right lower lobe, with increased FDG metabolism, suggestive of lung cancer. b. Multiple pure ground-glass nodules in both lungs, with normal FDG metabolism, suggestive of atypical adenomatous hyperplasia or inflammatory nodules; annual HRCT follow-up is recommended. c. Inflammatory nodules (solid) in the left and right middle lobes; calcification in the left lower lobe. Multiple focal emphysema in both lungs; bullae in the apical segment of the right upper lobe.

2. Increased FDG metabolism in the left tip of the tongue and bilateral laryngopharynx, suggestive of physiological uptake. Minor inflammation of the right maxillary sinus.

3. Malrotation of the left kidney.

4. High probability of uterine fibroids; left ovarian cyst; ultrasound follow-up is recommended.

5. Mild osteophyte formation in the spine.

6. No obvious abnormalities were found on cranial imaging; MRI follow-up is recommended.

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.
