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; irregular mixed-density nodules and masses with indistinct borders, partially fused, in the left basal ganglia and centrum semiovale, containing calcifications, the largest measuring approximately 4.1*3.0cm, with increased FDG uptake (SUVmax = 7.9); compression of the left lateral ventricle, with large areas of low-density edema in the surrounding brain parenchyma; punctate slightly low-density shadows in the deep brain, with no abnormal FDG metabolism.
No widening of the remaining ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, with a slight rightward shift of the midline.
Both eyes were symmetrical, with no obvious abnormalities.
A cystic low-density lesion was seen in the left sphenoid sinus, with an intact sinus wall.
No thickening of the nasopharyngeal wall was observed; the palatine tonsils were symmetrical, with physiological FDG uptake.
The laryngopharynx was normal in morphology and structure.
The parotid and submandibular glands were normal in morphology and density, with physiological FDG uptake.
The thyroid gland is normal in shape and size, with uniform density, and FDG uptake is normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region.
Post-operatively, the right upper lobe is absent.
Linear dense shadows and cord-like shadows are seen in the surgical area, with no abnormalities in FDG metabolism.
Multiple ground-glass nodules are present in the right lower lobe, the apical-posterior segment of the left upper lobe, and the left lower lobe.
The largest nodule is located in the apical-posterior segment of the left upper lobe, with a long diameter of approximately 0.7 cm and a maximum CT value of -610 HU; FDG uptake is normal.
A small solid nodule, approximately 0.3 cm in diameter, is located in the apical-posterior segment of the left upper lobe; FDG uptake is normal.
A few cord-like lesions are present in both lungs; FDG uptake is normal.
No pleural thickening or pleural effusion/pneumothorax is observed bilaterally.
No significantly enlarged lymph nodes are seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette is normal.
The esophagus is not dilated, and the esophageal wall is not significantly thickened or swollen; FDG uptake is normal.
No obvious masses or nodules were observed in either breast, and FDG metabolism was normal.
The liver was normal in shape and size, with smooth borders, no widening of the hepatic fissure, and no 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 and no abnormal local FDG uptake.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormal FDG uptake.
Punctate calcifications were observed in the spleen, but FDG uptake was normal.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma; high-density shadows were observed in the renal pelvis, calyces, ureters, and bladder, but FDG uptake was normal.
The left adrenal gland was enlarged with increased FDG uptake (SUVmax = 2.9), while the right adrenal gland showed no obvious abnormalities on contrast.
The stomach is adequately full, with slight thickening of the gastric wall in the antrum and increased FDG uptake (SUVmax = 3.0).
Intestinal fullness is unsatisfactory; no local masses are observed, and FDG uptake is normal.
The uterus is normal in shape and size; an intrauterine device (IUD) is observed in the endometrial area, showing increased FDG uptake (SUVmax = 3.0).
A small nodule, approximately 1.5 x 0.9 cm, is observed in the left adnexa, showing increased FDG uptake (SUVmax = 4.1).
No enlarged lymph nodes are observed in the abdominal cavity, pelvis, or retroperitoneum.
No significant fluid accumulation is observed in the abdominal or pelvic cavities.
The spinal alignment is normal; a nodular low-density lesion, approximately 0.9 cm in long diameter, is observed within the S1 vertebra, with normal FDG uptake.
FDG uptake of the entire skeleton is normal.

Impression

1. a. Mixed-density lesions in the left basal ganglia and centrum semiovale with increased FDG metabolism, considered a metastatic tumor based on enhanced MRI findings at this center. b. Lacunar infarcts deep in the brain. Submucosal cyst in the left sphenoid sinus.

2. a. Postoperative changes after right lung cancer surgery; no signs of tumor recurrence were observed in the surgical area. b. Multiple ground-glass nodules in the right lower lobe and left lung; FDG metabolism was normal. Early lung cancer is suspected in the apical-posterior segment of the left upper lobe; the remaining nodules are considered inflammatory nodules or atypical adenomatous hyperplasia. Close CT observation is recommended. c. Chronic inflammatory nodule (solid) in the apical-posterior segment of the left upper lobe. A few post-inflammatory lesions in both lungs.

3. Calcifications in the spleen. Left adrenal hyperplasia. Residual contrast agent in the urinary tract.

4. IUD insertion in the endometrial area with physiological uptake. Physiological uptake in the left ovary is possible; further specialist examination is needed.

5. Chronic inflammatory changes in the gastric antrum; endoscopic follow-up is recommended.

6. A nodular low-density lesion was found in the S1 vertebral body. No abnormalities were observed in FDG uptake. Benign bone disease is suspected, and metastasis should be ruled out.

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.
