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

Under fasting conditions, an intravenous injection of 18F-FDG was administered, followed by rest.
Whole-body PET/CT imaging revealed the following: Brain morphology and structure were normal, with punctate low-density lesions in the deep brain regions; FDG uptake was not significantly abnormal.
Some ventricles, sulci, fissures, and cisterns showed widening; the ventricles were symmetrical bilaterally, and midline structure shift was normal.
Both eyeballs were symmetrical and showed no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed; the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; the palatine tonsils were symmetrical bilaterally, and FDG uptake was physiological.
The laryngopharynx showed no abnormalities in morphology and structure.
The parotid and submandibular glands bilaterally showed normal morphology and density, and FDG uptake was physiological.
The thyroid gland was normal in morphology and size, with uniform density; FDG uptake was not abnormal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region.
Increased translucency in both lungs.
An irregular mass with lobulated margins is seen in the posterior segment of the left upper lobe near the hilum, indicating stenosis or occlusion of the posterior segment bronchus.
The mass measures approximately 6.4*4.0cm, with increased FDG uptake (SUVmax = 6.5).
Patchy areas of increased density with blurred margins are seen in the distal lung tissue, also with increased FDG uptake (SUVmax = 3.2).
Ground-glass opacities measuring approximately 0.3-0.4cm in length are seen in the right upper and lower lobes, with normal FDG uptake.
Patchy opacities with relatively clear margins are seen in the lingular segment of the left upper lobe, with normal FDG uptake.
Thickening of the adjacent left pleura is observed.
No thickening of the right pleura is seen.
There is no pleural effusion or pneumothorax on either side.
Enlarged lymph nodes are seen in the left hilum and mediastinum, with increased FDG uptake (SUVmax = 4.2).
The cardiac silhouette is normal.
Calcification of some arterial walls (including coronary arteries) is present.
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and increased FDG uptake in the middle and lower segments (SUVmax = 4.0).
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Plain CT scan showed uniformly reduced liver parenchyma, similar to the spleen at the same level.
A nodular low-density lesion with smooth margins and a long diameter of approximately 1.0 cm was seen in the left lobe of the liver; 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 or size, with slight thickening of the gallbladder floor 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 showed no abnormalities in shape, size, density, or FDG uptake.
A nodule of isodense density, approximately 0.6 cm in diameter, is seen near the splenic hilum; FDG uptake is normal.
A nodular, slightly hypodense lesion, approximately 2.2 cm in long diameter, is seen at the lower pole of the right kidney; FDG uptake is decreased.
The left kidney is normal in shape and size; no obvious abnormal density shadows are seen in the parenchyma; no widening of the renal pelvis, calyces, or ureter is seen; FDG uptake is normal.
Bilateral adrenal gland contrast is normal.
The stomach is poorly distended; the antral wall is slightly thickened; FDG uptake is slightly increased (SUVmax = 1.5).
The intestine is poorly distended; no obvious thickening or mass is seen in the intestinal wall; FDG uptake is physiological.
The prostate is full; punctate calcifications are seen within; FDG uptake is unevenly increased (SUVmax = 4.7).
The bladder is poorly distended; no obvious positive stones are seen within.
No enlarged lymph nodes were observed in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margins showing osteophyte formation; a linear area of increased density was observed at the upper margin of the L5 vertebral body.
L4/5 and L5/S1 intervertebral disc herniation were present.
FDG uptake of the entire skeleton showed no abnormalities.

Impression

1. a. A mass in the posterior segment of the left upper lobe with increased FDG metabolism, suggestive of lung cancer with obstructive inflammation; left hilar and mediastinal lymph node metastasis. b. Bilateral emphysema. Several chronic inflammatory micronodules in the right lung. Chronic inflammation in the lingular segment of the left upper lobe. Left pleural thickening. Calcification of some arterial walls (including coronary arteries).

2. a. Benign prostatic hyperplasia with calcification, uneven FDG metabolism; please follow up with PSA and MRI to rule out prostate cancer. b. Mild fatty liver. Small liver cysts. Possible adenomyosis of the gallbladder floor. Accessory splenic nodules. Right renal cyst.

3. Inflammation in the middle and lower esophagus; inflammatory or physiological uptake in the gastric antrum. Endoscopic follow-up is recommended for all of the above.

4. Spinal degeneration, L5 vertebral endplate inflammation. L4/5 and L5/S1 disc herniation.

5. Age-related brain disease, bilateral deep lacunar infarcts.

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.
