Whole-body 18F-FDG PET/CT scan in a patient with Pancreatic 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 a few punctate or patchy low-density lesions in the deep brain regions; FDG uptake was normal.
There was no widening of the ventricles, sulci, fissures, or cisterns; local density and FDG uptake were normal; and there was no midline shift.
The bilateral eyeballs had normal morphology and outline; the retrobulbar structures were clear; and FDG uptake was normal.
The right sphenoid sinus and left maxillary sinus mucosa showed slight thickening; the remaining paranasal sinuses showed no significant thickening, and the sinus walls were intact.
The soft tissue of the nasopharyngeal walls showed no significant thickening; the bilateral pharyngeal recesses were symmetrical; and FDG uptake was normal.
FDG uptake was increased in the left maxillary alveolar process (SUVmax = 2.8).
The laryngopharynx had normal morphology and structure; the parapharyngeal spaces were clear.
The parotid and submandibular glands were normal in size, shape, and density, with normal FDG uptake.
The thyroid gland was normal in shape and size, but its density was slightly uneven; FDG uptake was normal.
Some lymph nodes in the bilateral upper deep cervical spaces were enlarged, the largest with a short diameter of approximately 1.2 cm, showing increased FDG uptake (SUVmax = 2.7).
FDG uptake in the remaining small cervical lymph nodes was normal.
Multiple solid nodules of varying sizes with clear borders were observed in the lung parenchyma.
The largest was located in the posterior segment of the left lower lobe, with a long diameter of approximately 0.8 cm, showing increased FDG uptake (SUVmax = 1.3).
FDG uptake in the remaining nodules was normal.
Lung translucency was increased bilaterally, with thickening of the subpleural interlobular septa and localized honeycomb-like changes; FDG uptake was increased (SUVmax = 1.2).
A few patchy and linear shadows were observed in both lungs; FDG uptake was normal.
Slight thickening of the pleura bilaterally, with no obvious pleural effusion in either pleural cavity.
An air-filled cavity is seen on the right side of the trachea.
Flat lymph nodes are visible in the bilateral hilar and mediastinal regions, the largest being approximately 0.7 cm in short diameter, with increased FDG uptake (SUVmax = 2.6).
The heart size is normal.
Calcification is present in the walls of the aorta and its branches (including the coronary arteries).
The esophagus is not dilated, and the wall is not significantly thickened or lumped; FDG uptake is normal.
Gastric distension is poor; a nodular calcification foci approximately 0.7 cm in long diameter are seen in the anterior wall of the gastric fundus, with slight thickening of part of the gastric wall; FDG uptake is normal.
Intestinal distension is unsatisfactory; no localized masses are seen.
Fluid accumulates in the lumen of the small intestine in the right mid-abdomen; the intestinal wall is not significantly thickened; FDG uptake is linearly increased (SUVmax = 6.9).
A soft tissue mass was observed in the head of the pancreas, with indistinct borders, measuring approximately 4.2 2.2 2.5 cm.
The mass exhibited heterogeneous density, increased FDG uptake (SUVmax = 3.1), upstream pancreatic duct dilation with surrounding pancreatic parenchyma atrophy, and slight thickening of the adjacent common bile duct wall with dilation of the upstream intrahepatic and extrahepatic bile ducts.
The gallbladder was enlarged with fluid accumulation and elevated intraluminal density.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
No significant abnormal density shadows were observed within the liver parenchyma, and FDG uptake was normal.
The spleen was generally normal in shape and size, with normal density and FDG uptake.
An oval-shaped low-density lesion was observed in each adrenal gland, with clear borders; the larger lesion had a long diameter of approximately 1.5 cm.
FDG uptake was normal.
Both kidneys are normal in shape and size.
A cystic low-density lesion with a long diameter of approximately 2.2 cm is seen in the right kidney, with clear borders and absent FDG uptake.
No obvious abnormal density shadows are seen in the parenchyma of the left kidney, and FDG uptake is not significantly abnormal.
No widening of the renal pelvis, calyces, or ureters is seen bilaterally, and no positive stones are seen locally.
The prostate is normal in shape and size, with punctate calcifications seen internally, and no focal abnormal increase in FDG uptake is seen.
The bladder is adequately filled.
A soft tissue nodule measuring approximately 2.3 1.5 cm protruding into the lumen is seen on the left posterolateral wall, with no obvious necrosis or calcification.
Small lymph nodes in the hepatogastric space, porta hepatis, and retroperitoneum are visible, and FDG uptake is not abnormal.
A small amount of pelvic effusion is present.
The spinal alignment is normal, with some vertebral body margin osteophytes, L3/4 intervertebral disc bulge, and L4/5 intervertebral disc slight protrusion.
No abnormal FDG uptake was observed.
A 2.21.4cm oval low-density lesion with clear borders was observed subcutaneously in the right shoulder area, but FDG uptake was absent.

Impression

1. a. A soft tissue mass in the head of the pancreas with dilation of the upstream pancreatic duct and biliary system, and increased FDG metabolism, suggestive of pancreatic cancer. b. Multiple solid nodules in both lungs, most likely chronic inflammatory nodules, with the larger one in the posterior segment of the left lower lobe showing increased FDG metabolism; metastasis cannot be ruled out. Please follow up with CT scans. c. Small lymph nodes in the hepatogastric space, porta hepatis, and retroperitoneum are present, but FDG metabolism is not increased, suggesting reactive lymph node hyperplasia. Please follow up with CT scans to rule out other complications.

2. A mass on the left posterolateral wall of the bladder, most likely a bladder tumor. Please conduct further examination with enhanced CT or cystoscopy.

3. Bilateral adrenal adenomas. Right renal cyst. Prostatic calcifications. Enlarged gallbladder with cholestasis. Small amount of pelvic effusion.

4. Manifestations of chronic gastritis, with physiological uptake of the small intestine in the right mid-abdomen. Calcified nodules in the anterior wall of the gastric fundus; gastroscopy and enhanced CT scans may be necessary.

5. Bilateral emphysema, interstitial lung changes, a few chronic inflammations and sequelae in both lungs. Tracheal diverticulum. Reactive hyperplasia of bilateral hilar and mediastinal lymph nodes. Partial arteriosclerosis (including coronary arteries).

6. Degenerative changes in the spine, L3/4 disc bulge, slight L4/5 disc protrusion. Sebaceous cyst in the right shoulder.

7. Left upper periodontitis. Reactive hyperplasia of bilateral superior deep cervical lymph nodes.

8. Deep lacunar infarcts in the brain. A few chronic inflammations in the right sphenoid sinus and left maxillary sinus.

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.
